So i had an issues where i couldn't fire any columns in Arena 6. I could adjust the transition controls, but couldn't load new compositions.
After re installing, with no luck, and then going back to 6.1.1, still no luck. However now it wont advance past the "Loading screen" (On 6.1.1 & 6.1.3) Not sure what to call it. Please see attached image.
Let me know what details you need.
