Are you sure you did not miss a patch the problem is at your end.
Tip for a new install just copy your other install (or backup) to the new location & renaime it. stick a 2 on the end PBEM OOB mod or something. Camo games are super user friendly no CD & no registery items.
Having a backup means after my initial install I have only ever had to update the current patch.
If you do OOB or map scenerio making a second game used for that also saves accidently losing your work when installing a new patch.
