Hi,
I upgraded this AM to 2.3, and have not been able to launch the designer
since. I went as far a reinstalling helios-SR2 and reinstalling the latest
versions of the plugin and designer. I get this message even with a brand
new out of the box web app. I've searched around and can't find any
references. Woe is me... Any help would be really appreciated! Thanks, Joe
