Hi Timmeh,
Here is what someone posted on this error:
http://exchange.ni.com/servlet/ProcessRequest?RHIVEID=101&RPAGEID=135&HOID=506500000008000000CC5A0000&UCATEGORY_0=_30_%24_12_&UCATEGORY_S=0
I am not sure if it helps. The person re-installed the application and the problem went away.
Sorry I cannot help further.
