Issue: Latest version Articulate 360 Storyline.

Hi,  I downloaded the latest version of Articulate  360 storyline and now: 
1. I cannot open courses done less than a day prior to the installation, error message says corrupted, invalid or earlier version - no possibility of update to this version included like I have seen in the past when I updated.

2. The button states in this new version seemed fine when I added them, but when I open them to edit they are all appearing with a red cross on them accompanied by an Articulate pop-up 'error' message.

Is anyone one else getting the same?
If so how did you deal with it, bar reverting back to earlier version?

Thank you
