I tried to backup my computer and it didn't make any progress for many hours. After a few hours I gave up and closed the backup panel. I restarted the computer and now the panel comes blank with the external backup drive plugged in. If I double click the backup folder on the external drive and click restore I keep getting the error dialogue, "The parameter is incorrect. (0x80080057)".
If I don't plug in the drive it and click Options > Change backup settings I get the same error dialogue. Note, the backup control panel displays and says the drive is not plugged in and shows the last time I attempted to backup. It says that backup was complete but some files were skipped. The error code is 0x8100002F.
I tried to solve the problem using: http://support.microsoft.com/kb/982736/en-us It did not help.
I have looked into some of the logs and found this:

This is the second to last time I backed up.
Someone else had this problem: http://www.techsupportforum.com/forums/f299/solved-windows-7-backup-0x80070057-error-546542.html
They had a restore image and could go back to an earlier time. I do not have this option.
What can I do?
