Help Needed with crashing

[boycie]

Ive been using PT 10 since Jan and havent had any major problems with crashing before. Due to only having 2GB of RAM in my PC i had the warning box telling me i need to install more as Physical Memory was low. I havent had any issues til a few days ago where a project with around 20+ caused a runtime error/access violation error after adding two tracks, and inserting a plugin on them both (no audio files yet linked to those tracks). Now everytime i try and load up that project PT has the same issues and terminates itself shortly after opening. I have installed another 2GB of RAM increasing my total RAM to 4BG on my system, i thought this may have helped the matter but its done diddly-squat. If anyone has any ideas on how i can sort out this issue without re-recording everything id be very grateful.
P.s my PT software and drivers are up to date
