Since using AE CS5.5, I find that my projects when reopened have many source files missing, even though I have not changed the location of the original files. It turns out to be really inconvenient. Is there a solution for this? Never had this problem with any other version.
However, you may not have all the UPDATES to AE 10.5, aka CS 5.5. This would be true especially if you have installation disks. You should still be able to get the updates by looking under the Help drop-down menu, and they may solve a lot of problems for you.

I seem to be good with my updates. It's done it since day one with this CS5 version. It's got some other weird problems too that I don't like. Sometimes it drops the audio off a spot when it renders or commands don't respond.
