EventPrime Not Activating

Hello

I am currently trying out the ProfileGrid plugin which looks pretty so far although I have noticed a few with displaying on frontend (still working on solving those myself ATM) But I did install the free extension EventPrime Integration and I tried the 2 download option and get the same result with both, they do not want to Activate. All the other extensions activated just fine except this one.

Any suggestions please.

Cheers
