When you get error messages, examine in which files they happen. This gives you hints for the reason of the problem - like missing or outdated files in your installation. I have not enough information to help you here, but you should be able to fix this, at least by re-installing 6.40 and re-updating to 6.60.

If you can't get it to run, describe your problem in "Ask Conitec" - I'll help you then. This thread is about A7 and your C-Script problems are probably unrelated.
