Hi Vlad,
It is great that you resolved this problem.  
Many of us use this group to search and learn from each other's 
experiences, and it can be frustrating to read a thread of messages and 
then simply see 'resolved' at the bottom. 
If you have time, it would be interesting and helpful to know briefly what 
you did.  I mean just an executive summary.  
Many thanks!
