Also don't forget when uninstalling the br make sure to delete the patin driver and also this one PCatip.vxd if it's in there.
when running BW uninstall it doesn't ask for the deinstallation of the couffin driver. But after deinstallation there's no more pcatip.sys in C:\winnt\system32\drivers so I guess it did its job
I'm trying v4.2.5 now
setup looks promising:
Hardware access layer installation status :
Patin-Couffin Access layer selected.
30 days of trial left
Hardware access layer successfully installed.
thanks for the help so far
edit: I neither have ccd nor alcohol being installed. Only Nero and CDRWin. Concerning background tasks...daemon tools are running. might that cause problems?
