Problem #1:
I have downloaded the 1.23 patch for JJ2, but when I try to install it, the installer tells me that the patch is not needed. When I play the game it does not appear to have been upgraded. I have downloaded the patch from several different sources with the same results each time.

Problem #2:
After noticing the patch problem, some bright light in my family decided that reinstalling JJ2 might fix it. However, after uninstalling, the CD would not allow me to reinstall. We even went so far as to delete all JJ2-related files - levels and everything - but the only way to recover the game so far is to copy it directly from the CD and paste it on my harddrive.

I have no idea why these problems are occurring, which is probably why I'm posting here. Suggestions?
