exceptions in dll and demo and app pool hangs on huge traffic

[florentinbuzoianu]

The demo and the dll throws a lot of errors of the following:

• System.InvalidOperationException
• System.ArgumentException
• System.NullReferenceException

also, it seems that on huge traffic on a server it hangs somehow the app pool. i think it is caused by a lock on the xml files reading, although the instantiation of the dll is a singleton.
