No idea why your launcher will not load them.
I know I have read about this somewhere before but for the life of me I can't recall what was said and after searching of over an hour using various key words with no success, I am resorting to asking here. I have downloaded a couple cats and a horse from the Exchange (I know, not a good idea) but these really hit my fancy so I decided I must have them. The problem is (surprise surprise) the launcher will not load them. Keeps giving it's same old excuse of needing to be updated. I'd like to bypass it if I can. Is there a tool I can use or a way to get the s3packs to .sim files so I can just add them in?
