since there is also a connection at port 80 for downloading the game it should still work if "p2p connections" (unusual ports) are blocked
(verified, because i have blocked all p2p connections for allods myself, i just download the game/its updates from my.com this way!)
more likely is that something else is causing troubles here...
you could try to use another dns for example, in case your campus uses censorship there
try to look for some xxx / warez / gambling / etc sites and see if his is blocked
if so you may find out what system they use to block, so you can bypass it
VPN would also work ofc
you could even try to "abuse" TOR for this matter
sadly, i have not found any PROPER direct download
