One thing to first check is in the "run" box, type msconfig. then go to the
boot tab and click the advanced tab then you can now untick the debug box
Then if it is already unchecked another things to try that I have heard
works is:
search for and rename a file called amdfix.sys- found in the
winnt/system32/drivers directory.
Another solutions if you have an Audigy 2 Card:
If you installed the driver/application software from Creative Labs Audigy 2
Platinum, you simply need to "uncheck" the box that lets that annoying
Creative Introduction/Getting Started/Demo screen launch on startup, then
reboot your system to see if A-the annoying startup graphic stops launching
at startup and B-your game stops prompting you to "unload the debugger" when
you try to run it.
