That's normal it goes back to say Read Only but it's not, I don't think that is your problem if it's still crashing.
Can you just rename the Realband folder Realband-old and then install it again and when it is working make a copy of the working folder Realband-works so you have a backup.
You can also ask PG to get on Teamviewer if you install it.

Here is a Take Ownership right click menu option for Win7 but I don't think that's the problem.
