UMD issue

I just recently bought a used game (Power Stone, the game is friggin sweet). However, the UMD casing is split at the top. The game still works fine, but is there a simple way to repair this? I would've brought it back to the store but it was the only copy left and the game is fairly hard to find as it is. I'm sure there's someone out there who ran into this problem before. Any advice?

Thanks for your time and response :)

Replace the UMD case.kashim26

How would I do this? Do they sell replacement cases?

Your lucky that it works, cause I bought a umd from gamestop and it's plastic shell was split in half and crushed in. When I put it in my psp it made a loud grinding noise.
