We have licenses for 2009.2 with service release 1.  However i can no longer use the product after installing it.  If i try to work with a project that already contains a grid, visual studio crashes and has to restart.  If i create a new project and drop a grid on the form, i get this:

"Failed to Create Component UltraGrid :  The error messages is as follows "Failed to compare two elements in the array".

Basically I am unable to work on any project that contains the infragistics components.  I am on an extrememely tight deadline and have worked 3 weeks straight.  Can anyone help me get this resolved?  I sure would hate to work yet another weekend.
