Adding one more agggregate field throws exception:"Object reference not set to an instance of an object"

[Diyan]

Hi,
I'm using the pivotgrid that is connected to my analytics server. What I do is add 2 row fields one column and 2 aggregate.
 It throws an "Object reference not set to an instance of an object"  every time when I one more aggregate field. It happen with every aggregate field. I saw that in the sql profiler there is no  error and all MDXQueries are executed successfully. Below you can find the stack trace of the exception and hopefully it can give you a clue what is wrong.
