HI - my son is running W4 Mayhem and might need to try a reinstall to try and Fix a Winxp issue.

Q: What happens to the game data? - Can this be copied and saved then replace the reinstalled "blank data" files successfully? ie so the person does not need to replay all the levels and add on bits again - dose the make sense in Worms??

Its dad here! :D

Worms 4 Mayhem\data\SaveGame.xom

Copy the xom data to your desktop, reinstall the game, replace your old file with the blank one, done :)
