Pro Tools 8 M powered, vista 32 bit home

[Mrbendointhis]

Ive had this for a week now, and have had nothing but trouble! Using sessions created on a G5 usings Pro Tools 7.4, Sometimes the session will load fine, Other times i will Press Play and Pro Tools Will Automatically Pause itself.

I noticed the same problem loading sessions from Pro Tools 8 from a mac onto my computer.

Im Running Waves diamond, im thinking this might be part of the problem?

My playback engine in Pro Tools is setup to basically handle a large project.

Please HELP BEFORE I GO CRAZY, tryna reinstall protools update to 8.04, then 8.04s sayin i cant load something up i did in 8... Etc im sick of trying to trouble shoot!!!!
