PyTables - Hierarchical datasets

Hi,

I'm in the process of closing as much tickets as I can for 2.2.1 (will 
be released next week).  One of the users claims in ticket:

http://www.pytables.org/trac/ticket/290

that he is having problems with my binaries for Win32 and Python 2.7 
(running in a Win64 environment).  I've tested this on my own machine, 
and binaries seems ok.  Anyone else is having this problem?

Thanks,
