I've been running 4 webcams continuesly for almost 2 years now using iCam Sourse 2.2.3 On a Windows 7 PC without any problems. All 4 motion record to an external hard drive. Everything has worked flawlessly in the past. Today I got an error about the hard drive so I unplugged and replugged it in. When I went to relaunch iCam, it stayed up for a minute or so then crashed. I tried relaunching, same crash. I then reset my computer, same crash. Finally, I disabled the motion record but iCam is still crashing upon launch every time. Like I said I've been running this set up a long time now and never had this problem. I haven't made any changes or updates that might interfere with Source. Can anyone help?!
