Whoops - set field to can not modify and always validate

Welp - probably not my best choice of first posts... but I play the cards as theyre dealt. 

 

I accidentally set a field to not be able to be modified and always be validated.  Needless to say I am now stuck and fielmaker wont let me do anything.  How can I access the the database manager so I can change the properties of the field?
