Hey guys, i'm currently runnign a home studio set up with the central point being my intel 1.7ghz Windows XP, 1gb ram laptop and nuendo 3.2.

I use Drumkit from hell and EW Symphonic orchestra gold on all my tracks. On Monday, my Edirol UA 25 interface came (Replacing an old interface), it does it's job fantastically. However, since i installed it, when i bounce my drumtracks in DKFHS, it records one sample then recording turns off. When i sample up a Midi in EW Sym Orc, no playback sound comes out. This has started happening for all my VSTs now.

I've tried this on another VST host (n-Track) too and i have the same problem.

What could be causing this?

Thank you!

Oh yeah, First post!

Edit: My samples are stored on an external USB 2.0 drive. I have used this setup for a while and not had ANY problems until i installed the UA25.
