Hi, since updating to Win 7 x64 and PT LE 8.0.4cs2 I've had nothing but problems.
I have tried all the optimizations recommended trashed preferences endlessly and searched the forums for answers. I am sure there is a cure. If anybody can help I'd appreciate it. The loading time is about 5 minutes and after you trash the preferences it comes down to 52 secs. When you switch on the next day its back to 5mins and counting.
I have updated the bios for the board but still problems.
Kontakt 4 has caused the computer to freeze and PT has just crashed.
