I need to be root to launch game in Wine

[OldGrantonian]

I have dual-boot Windows XP and Ubuntu partitions.

I have a game that I played in Windows. Previously, I could also play this game in Ubuntu. I simply highlighted the game in Nautilus, and opened the game in Wine.

After a re-install, followed by the recovery of some files, the game cannot now be launched in Nautilus.

I need to open gnome-commander as root, then launch the game.

The permissions for the game are r-x r-x r-x. I don't know what they were before the recovery.

In order to launch the game as non-root, do I need to alter the Wine permissions?

My guess is that the recovery process changed the ownership of the files to root. Check out the file ownership (in Linux), and change back to your userid if necessary. If that is not the case, then I don't know what the problem is.

Note that the ownership and/or permissions of the directory and/or files where the game files reside may have changed as well, not just for the executable.
