keynote not responding

I am running into an issue with keynote and was wondering if you could help me out

- Keynote just doesn't want to play even with a completely blank presentation

I've done the following so far:

- updated current keynote to latest one

- remove keynote with appcleaner

- run disk utility on the permissions

- reset PRAM

- remove plist and cache several times

- ran keynote in safe boot = no luck

- saw in the console that keynote is having some "font" issue

- ran font book - validated all fonts until everything turned out okay

- removed keynote again

- rebooted

- installed again = still no luck

Please advise on what needs to happen next in order to fix this problem

Thank you
