PlexWriter and Microstudio V3.000 HELP

[JoEvil]

I have been using Microstudio programs for my CDGs since 2000 with the same PlexWriter 48/24/48A up until about a month ago when my last version of Microstudio (V2.500) would not let me use it anymore (due to inadvertently 'cleaning' off some old files). I decided to get the new V3.000 version, but, unfortunatley, I cannot import (it locks up my computer forcing me to do a restart) or record a CDG from the songs I imported as recently as a couple months ago. I've gone through the manual, tried changing the speeds and such to no avail. Memory and speed of my computer are not issues - there is plenty of both. Can anyone help with what I can do to make the V3.000 version work with my drive? Any advice is appreciated! In the alternative - can anyone tell me how to fix my old V2.500 version (I can't afford a new drive for a very long time)? JoEvil
