Nope, no errors while installing. I've been using the program for about 3 weeks actually. But a few days ago, I plugged my phone in using a USB cable and the program hanged at the 'initiating connection' screen. So I unplugged the phone and restarted the computer. I haven't been able to run the program after that.
OK, go to Start-Run-%appdata%-OK
You'll see now your Appdata-Folder. Then rename the folder "MyPhoneExplorer" to "MyPhoneExplorer_backup". After this try again to start MyPhoneExplorer
