...****... Yep, that was the problem.. i was adding +16, not +10, which does work on steam.
I would use the toolset for it, but my toolset doesnt work for some reason (i'm pretty sure its because of some random SQL error on install), but your method seems to work perfectly with no problem whatsoever (except for a few stupid errors, like me not realizing that the +16 was dec, not hex).
I hope you're not pulling my leg (if someone did I would'nt understand anyway).
uhh.... What? Would you mind clarifying what you meant?
