you are right, i'm talking about dial up modem. I already tried to uninstall and reinstall modem driver using Device Manager. I've tried to do that several times, it only worked ONCE!!
Deadguy, the driver is still there. I didn't do anything with the driver. Will the program help you to fix this problem?
I wonder why when I checked the modem in Device Manager, it says the modem is working properly and no conflict. However, it is not!
I think my modem is unstable or it might have conflict with some other program. But I'm not sure.
