WinFax Pro V10.02 Big Problem

[KidKasha]

After this program recieves a fax, it does not release the modem. This means I am unable dail out using the computer. My OS is XP-Pro and the modem installed, is a HSP56 Micromodem. The ISP I am using is ATT.net. It is not the ISP as my alternate ISP reacts the same way. If I fax out the problem does not occur, only when a fax is recieved. I checked my settings in WinFax and all seems fine. This happened a little time ago, but before it working great. I could not find the program in the Add Remove in XP-Pro. I also was unable to find uninstall on Winfax 10.02 program CD. In fact it stopped me from uninstalling the program. How should I proceed. Any solutions??
