Safe Boot, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, reboot when it completes.
(Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive.)

No still the same. As said I can mount the volume and copy stuff onto it, so doesn't look like a permission problem. I think the issue here is that time machine doesn't allow me to change the volume. When I klick on "Change Volume..." a window should appear but this doesn't happen. Instead
System Preferences: *** -[NSCFString substringFromIndex:]: Range or index out of bounds
This error message sounds like the application trys to access an array with an incorrect index.

Yes it is, but you got rid of the .plist for TM right?
Open Console in Utilities & see if there are any clues or repeating messages when this happens.
