Could Not Open the Editor error

Using standard 2.0.0.1 server, with a 2.0 client, I am receiving an error message of "Could not open the editor: An unexpected exception was thrown" which is preventing me from creating (and/or saving and then opening) artifacts in my RRC Project. I can seemingly create most artifacts fine. For example, I have no issues sketching a user interface...but when I save and then attempt to open that artifact, I get this error. It seems to be consistent across all types of RRC artifacts (use cases, use case diagrams, storyboards, et al). Any help would be much appreciated.

I will add that i found one similar instance/post here of this happening. That individual said that they tried to archive the default project using the web admin UI and then created a new project using the rich client. Upon attempting this, I select to create a Project using the default folders and attributes and upon selecting Finish, cannot proceed. This screen simply reappears upon selecting Finish:
