ISDN card installation problem

I have installed new Primux ISDN card. After that Xeepe cannot makes calls to ISDN.
Any advices?
Before I used AVM Fritz!Card without any problem.

Uninstall Fritz!Card drivers first

Windows cannot manage more then one CAPI driver installed.
Use software provided with AVM Fritz!Card to remove all drivers from the system.
Then install new card drivers again.
I hope it will help.
