Solved the remainder of the instability problems.
Enhanced the installation procedure.
The plug-in for the Today screen is now automatically activated, and uninstalling CheckPOInt now removes all installed files.
It's no longer possible to synchronize when TomTom Navigator is running.
This was done because synchronizing while TTN is running sometimes leads to file locking problems.
