NEW_ITEM issue

Hi

I suddenly can't add anymore blocks to my profile fields. This is the error I'm getting: Sorry couldn't insert new item. Please check if NEW_ITEM already exists. 

If I delete the last block I made, I can create add the NEW_ITEM with no error. But when I rename it to whatever, can't add a new block again, same error. 

I tried phpMyAdmin, there is no NEW_ITEM in 'sys_profile_fields' or 'Profiles'. 

Repairing the database didn't help. 

Any help would be appreciated. 

Ok apparently problem is I have reached the limit of the fields I could add. When I delete more I can recreate more. 

I am able to add fields directly from phpmyadmin but can't via Dolphin's profile fields. Is there a way to increase the limit?
