It's even true in some way... this is what i could see in the log file:

There seems to be wrong with the "TMCanyon_2011-09-01.pak" file, which I guess contains all new or updated TM features since MP2. So if this file can't be loaded, you're basically working with an old version.
It definitely explains the issue of the missing blocks, and probably other problems as well.
