Elecard Problem

#1
I installed ProgDVB 4.84.1 Elecard Edition on Windows Vista. Eachtime I try to run it or change the channel a message appear. It says: "IID_IElecardRemuxer error!". I don't know what's the problem. I uninstalled the previous Elecard & Prog before I install the new one, but I still see this message. I was using ProgDVB 4.83.4 before and it was working correctly. I thought the problem is from the new one, but when I installed the old one again, surprisingly I still see the message. Can anyone help me, please?
