I know this is a really old message but in case anyone ever has this problem I figured out what my problem was. I got the exact same runtime error. I was moving from RH x5 word to RH9 word and when I tried to open my project in RH9 I got a run error. The conversion was not the issue, though it only picked up then. I back up my projects week by week so I was able to Isolate when the issue started..as one week would convert to 9 but the next week would not. I had to remove 2 topics from the current project and then it ran fine. Something you entered the last time you were on is hanging it up. Might not be a lot of help but if anyone else has this issue it is a place to start.
Welcome to the forum Theodorakis
It helps to know it was something in a topic that was changed. It would help even more to know what it was about those topics.
Presumably you needed to recreate them. Did you recreate them with exactly the same content but second time it worked or did you have to change something you suspected of causing the problem?
