In your other post you said that you downloaded the full install and then the 2 updates.. all you need is the full install. Delete your entire RPG folder, and then install particle's provided full install.. that is all you need.
The full install includes all files from the original install AND the 2 updates you mentioned.. if you did the full install and then the 2 updates, you will have over-written the newer files with the old ones from those 2 updates.
To avoid any other problems, it would be best to completely un-install tribes and re-install it, and then do particle's full update. If you're heavily modified (scripts, mods, etc..) then you can get away with deleting the RPG folder and any other RPG stuff from your config/base folder and re-installing the full update.
