Datagrip Completion not working

Hello

I had installed a 30 days version of Datagrip on my MacBook Pro and it work very well so I have now bought it.
However short before I bought it I had problem with the code completion, first it was very nice and presenting every keyword, e.g just type se and it suggested "SELECT" and so on, however this has now disappeared.
I can get gode completion by hitting the key combination CTRL+space. The hardware is a MacBookPro and I have been a pc user forever so I'm not surprised if I have succeeded to make some configuration globally on my Mac that has hitting the Datagrip.

Changing in the menu under Code-Completion-BasicType or SMarttype doesn't seem to change any thing.

My installation runs on a "mounted disk", the dmg file that came with the datagrip download. Could this be the problem?


Any suggestions what I can do for making it work again

Thanks in advance.
