Problems syncing with WinAmp

I've installed zSuite and have everything set up properly. I am using the latest version of Winamp and when trying to sync my Zune, the following issue occurs. Under 'Portables' in Winamp, it displays 'Loading Zune'. But it never finishes and then Winamp crashes with the following 2 error screens.

winamp.exe - Application Error
The instruction at "0x7c910193" reference memory at "0x774eef4a". The memory could not be "written".
Click on OK to terminate the program
Click on CANCEL to debug the program


Microsoft Visual C++ Visual Runtime Library
Runtime Error!
Program c:\Program Files\Winamp\winamp.exe
R6025
-pure virtual function call

Any help would be greatly appreciated. Thanks.
