"Bus error" in thread "MainThread", at address 0x0 while "initializing AVX2 Host"
on Mar 14, 2012 at 4:55:57 am

Hello everyone,

I needed to consolidate a couple of Avid sequences to an eSata drive. I am using MC 4.0.2 with Mac OSX 10.5.6.
I was using it all day and everything was fine, no problems. When I went to select my target, the eSata drive wasn't showing up although I thought it was there earlier.
I had even done this exact task a week ago to the exact same drive with no issues. Anyway, Finder showed the driver so I quit MC and restarted it. Now I get this error

"Bus error" in thread "MainThread", at address 0x0

when it's trying to 'Initialize AVX2 Host' and then it crashes. Everytime. I have uninstalled and scoured the hard drive for any remnants of Avid and removed them along with BCC and AVX plugins. I removing AVX files from the AVX2_Plugins folder. I tried validating fonts and removed some duplicates hoping that might work. And I removed all external devices.

I have repaired permissions to my startup drive a few times, including after uninstalling. I have tried every suggestion I can find and nothing has worked and I can't open Media Composer. The worst part is that I was using this same set up earlier. I have done exactly what I needed to do a week before and had no problem. I am now totally lost and would appreciate any kind help I can get.

I actually found my problem. It was a corrupt MCState file. I think it might be because I changed target drives in media creation tool and moved the drive. Although I moved it with MC off, I opened MC with it removed before changing the target. MC opened fine the first time but not the second. Anyway, I deleted the MCState files (user & system) and now it works fine.

Hey,
I have the same issue with MC 6.0.1
Could you tell me where I find the files you deleted?
Would appreciate it.
Cheers.

Are you using mac or pc? I'm on a mac and there is one in;
Avid (or Macintosh HD, mine is partitioned to run off different startup disks)/Users/Shared/AvidMediaComposer/AvidUsers/Avid/MCState

and there is one in;
Avid (or Macintosh HD)/Applications/Avid Media Composer/Settings/MCState

to save yourself some time just open a finder window and type it in the search at the top right corner, they will both pop up. Not sure on the pc but I would imagine if you were to open a finder browser and typed in MCState you would find it similar.

Also, there are other preference files you may want to delete as they can in fact cause problems too. Look for Site Settings, and Site Attributes (both located in the Avid/Applications/Avid Media Composer/Settings foler). You might want to consider deleting your project settings (.avs file)too. Since all of these are loaded into RAM upon start up, they can corrupt each other. Hope that helps.

Sorry, one last thing. Since these are preferences, try to think of any settings you have changed recently that Avid may not have liked. I think in my case it was the target drive in Media Creation tool because that was the only thing I have altered.

Deleting these files will allow you to open the program but doesn't solve why they were corrupted in the first place. Could be because something was changed or sometimes it can be chalked up to the wonderful world of computers. Just food for thought.

Cheerio,

Nate

Hey Nate,

Thanks a lot for this. Avid surely doesn't make it easy to switch from Final Cut Pro. I have tried to contact them several times without luck. I will try this out and hope this works. Installing trial demo of MC 6.0.1 and both of my macs give me errors. Ufff. Fingers crossed.

Cherrs.
