The Solution to all your ills.
If you have a TRIBES 2 CD, explore it, and go to Tribes 2 First Aid.
If you cannot copy it properly, you must download T2 from the main page.

Note that this only works if you have to CD. Online downloads and using the first aid on it won't do anything (and shouldn't do anything).
The Tribes 2 First Aid tries and copies each file as a whole, and if it did not copy it successfully then it goes back and copies it in chunks to ensure a correct transfer from CD to hard drive. Therefore, it will
with CD installs.
Plus, the CD doesn't include the patch (if I remember correctly). This will probably cause problems down the line. Your better off just downloading it from this website and checking the MD5 sum...
