As title says: I moved the whole LFS folder to another drive, but now .mpr, .spr and other LFS files are no longer associated with the program.

I tried changing associtation directly on a .mpr file (as attached photo LFS 1 shows), but nothing happens when I click "open" (as photo LFS 2 shows).
I'm on Win7 home eddition, anyone has a clue how to solve this?

You can't move an installed program to a different folder and expect it to keep working...

You can uninstall it and reinstall again (if the above solution doesn't solve it) using the new path.

Whis is basically what I said, isn't it?
