Storyline 3 upgrade causing multiple issues

I recently upgrade to Storyline 3 and since then I have been having multiple issues including the following:

Projects unable to save due to memory

Unable to preview storyline and Articulate crashing out.

Articulate not responding to and unable to add text or tiggers to slides

Articulate slides not showing content

I tried to uninstall the product and reinstall Articulate and it has not solved the issues.

My colleague who upgraded at the same time is not having any issues with the product at all. If anyone could recommend what I might be able to do to fix the issues as I am currently losing large amount of development time and also having to recreate hours of work as the projects will not save.

Many Thanks

Paul
