Very unusual problem

[Seventhwish]

I have been working with PT for a few years now and this error is a new one on me.I think I know the problem ,but wanted to run it by all of you to hear your thoughts on this issue.
Recently,while mixing a session,with no warrning message,I totally loose Pro Tools.Complete shutdown without even a window opening to say something like "Lost Connection with Pro Tools.Reconnect and click OK".Screen just diappears.The computer is fine,thinking that it was a crash,but have to reopen PT and then it seems fine,a little shaky,but fine.I can reboot the whole system and it's like nothing happened,but if this happenes,the session doesn't save and I have to reopen in the session back up folder.I think that this may be a driver prob.If so,do I need to just reinstall PT or mayby this is a common issue and there is a download fix.Thanx for any help.

I get something very similar when I using VST2RTAS wrapper on a certain VST plugin. ProTools just disappears without any error message. When I re-launch PT, it says PT closed improperly and can't be re-opened. I have to reboot.

The work-around is to not use that plug-in.

Some help, eh?
