i don't know if this is the case for anyone else, but, having bought the bundle a few weeks ago and having gotten the free upgrade (which i'm still very grateful for by the way! so much extra stuff!),
the My Products page in the user area still shows sampletank 4, not sampletank 4 max. max does show correctly in the ik product manager. but this means i can't manually download sampletank max content in the user area.
likewise, syntronik and a bunch of other instruments show up as their CS versions. sampletron isn't showing up at all in the user area, only in the product manager, but, just like you can see in all the other forum posts about sampletron lately, it fails to install (gets stuck at "Starting installation...")
basically, in the user area, i see a special Humble Bundle TIer 4 serial and product, which i activated and which gave me access in the product manager, but something seems out of sync on the website and in the account because everything else still shows as if it's products from the old non-upgraded version of the bundle
this is partially a bug report to make IK aware of this problem, and partially a question: is there a solution yet?
(i already contacted IK support about this. waiting for a response.)
