can anyone shed any light as to why this would appear all of a sudden, worked perfectly well the last time i was onsite. did someone connect with a newer version of step 7 safety? any ideas?

I-DB is the safety Program auto-generate DB which is not allow programmer to access.

Based on this error message is insufficient to find out the problem, could you provide more information?
