Alien Alphabet Mystery Cache

In the year 3000 giant monsters, robots, and aliens roam the planet, some are here to steal or cause trouble, but most just work here. Early on one alien placed a geocache in Michigan. While the alien meant well, the first cachers discovered that the cache page description is written in Alienese so no one on Earth can translate it, not even Brainzilla... A while back it was rumored one professor was able to translate the alien message, but he was only able to tranlate it into beta-crypt-three, a language so complex there was absolutely no chance of him understanding it.
It was said that this message, once decrypted leads to the alien cache.



You won't get too many hints out of me on this one, just to make it all the more rewarding in the end right?
