Help, Help! Demo won't run, drives aren't seen

[cachuela]

I'm running windows XP on an HP Pavilion 753n.
2.53 GHZ
512 Meg of memory


When I start the microstudio demo, I get the following errors:
Error Signature
AppName: microstudio demo.exe AppVer: 2.6.0.9 ModName wnaspint.dll
ModVer 1.00.1 Offset 0002faa

I've already tried all 3 solutions for installing compatible ASPI driver, to no avail. However, when I select properties on the microstudio demo icon and set it to microsoft 98 compatible mode, the software starts. When it runs in this mode, it does not see the Plextor PX-712A (usb) drive that I recently installed after purchasing it from your website. It does see my older CD-ROM R, and DVD drives (that are not CDG compatible). Windows Explorer does see the new drive (G, and I'm able to access DVDs and CDs with it.

I'm totally current on all windows updates, and all firmware and microcode updates.

Is there a support number I can call? I've been posting and getting responses from support (every couple days). (It seems after several threads, there is no follow-up) At this rate, it will take me all year to get this problem corrected. I spent a lot of money for this DVD drive, and I'm very interested in the software, but I don't want to buy it until I can get the demo version working and verify that it will work.
