My license is free and i believed the error is supposed to be saying that my modem does not support faxing right?. OK, my question is like this, if i pay for my license to get full faxing capabilities, can you give me your assurance that i can definitely fax. I am selling commercial vehicle and i need to fax out catalog and not just text only and may i know what is the resolution like too.
