I'm relatively new to AE.
I'm working on an iMac (Late 2009, 2.66 GHz Intel Core i5, 12GB 1067 MHz DDR3, ATI Radeon HD 4850 512 MB, OSX 10.8.4)
For the past two weeks, immediately following the successful completion of two small projects, AE CS5 began to FREEZE my entire computer (No error codes or beach balls of death) requiring a hard re-start. So after attemping vaious 'fixes' found here & across the internet (closing OpneGl, unistalling & reinstalling, etc.), I took my computer to apple looking for answers. After showing them the issue, they ran EVERY diagnostic they had & my computer came back ALL CLEAR! It's even running better! So I upgraded to CC & the problem continues. I've EXCLUSIVELY used Adobe products (Ps, Fl, Ai, & ID) for the past 10+ yrs and have been sold till this AE issue. I'm beginning to DESPAIR! I've seen this concern referred as far back as CS3 & am praying that someone can help me ASAP as I've just received a Big contract TOTALLY dependent upon AE. I don't know if there's software conflicts somewhere due to an update (remember, it WAS working & I completed my first two projects with NO ISSUE AT ALL!)
Please HEEEEELLLLLPPP!
