Hello!
I was asking for help with "empty user details for non-english accounts" in topic:
http://www.lansweeper.com/forum/yaf_postst4544_Empty-User-details-for-non-english-accounts.aspx
Problem had solved, and I had been assured that this fix will be in next update.
02.02.2011 I am updated my NetWrix to 4.1.0.11 and problem came back.
