Major Problem with DX2

Hello. I just paid for the reg version of DX2.
and everytime i load a new theme. (DX2 theme or older theme) I get this error.
********************************************
DXMAIN: DesktopX.exe - No DISK
There is no disk in the drive. please insert a disk into drive \Device\Harddisk\DR1
*******************************************

Then the option is to "try again" - "cancel" - "Continue".
when I try to push any button it just pops back up again. it hangs DX2 until I restart my box.
does anyone have any ideas about this?
I have reinstalled DX2 many many times and get the same error.

thanks all,

Angelo
