[sccm 2007] SCCM 2007 Error - Assembly Not Found

[mjgreen]

Hi all,

 

When attempting to create a sub group within my advertisements (to keep everything neat and tidy) I recieve the following error:

 

'Error: Assembly not found'

 

I have in the past successfully managed to create groups, but now it has stopped working.

 

Please see the attached picture file to see what the error looks like.

 

Any help appreciated

 

Many thanks
