problem running clone cd 3.*.*.*
 

this problem didnt appear in clone cd 2.*.*.*

when i double-click on the desktop icon, clone cd says me a msgbox with a X WRONG without messages, and i cant run it.

what can i do?

Sounds like you've used a blacklisted serial, or haven't completely removed all of the old Clonecd before installing the new one.

Find and use a CloneCD reg cleaner, then re-install.
