I have a feeling it might have something to do with a buddy name (like if it's too long) but it could be simply be that the total size of the deck file is too big (aka, there are too many letters in the file) and the buddy makes it overflow.

I will either have to change hosts, or try using a database.

Will try the latter, since changing hosts means changing website address.
