Could you give a little more info?
For example:
What error message do you see?
Do any elements work at all or do some work from Control Room but not others?
What spy mode did you use (UIA, HTML, etc.)?
I know a lot of people have been having issues with Google Chrome in 6.4+, so your issue may be tied to that. But I would verify that your issue is not speed of execution problem. Throw some arbitrary waits before and after some of the stages that are having problems and see if it still has the issue. If it does still have the problem even after that, I would report the problem to Blue Prism directly through your rep or by emailing support@blueprism.com.
