Currently I'm using autoCAD LDT 2006. My co-workers are using autoCAD LDT 2005. I'm trying to use Sheet Set Manager. I set it up in '05. No problems. Now I'm using '06 and I need my co-workers to help me do some drafting. Last Oct. '05, a co-worker helped me out with a watermain project. He had no problems opening, saving, and opening another drawing. Now last March 06, that same co-worker is now having problems opening other drawing after making drafting edits, plotting or anything in a drawing linked to S.S.M. Everyone in LDT '05 gets a INTERNAL ERROR or FATAL ERROR.

Anyone run across this problem?

Sorry if my story reads funny.
