We do have a monthly check that is running with all of our applications/plug-ins. With version 6.0.0, there are currently no updates available, so that is why the program will not prompt you to update.
As for the 3ds model you are working with, we are aware of the issue and are currently working to resolve the issue. Please see my e-mail regarding this issue.
If you have any additional questions, feel free to contact me.
