Profit should be working on Beta, it was last night when I was checking the tradeskill window. Just make sure you're using what's on the updater, not the zipfile download. The zipfile hasn't been updated in ages. What I do is just drag a copy of my reguar UI/ProfitUI folder over to BetaServer/UI/ProfitUI and copy eq2.ini over to BetaServer (I don't have anything in it that needs editing for the new location).
I figure the classic and variant 1 skins have been outdated long enough at this point that 1 more week of using the default skins won't kill anyone. With the size I'd rather not overload Kaldran's mailbox more often than I have to.
