I had this problem, two different error codes, a blank white box & a whole slew of problems. It occurred to me that I have sooo many forms that are no longer used, ie items that are fully depreciated, and when I deleted a goodcportion of them everything worked as smoothly as it should. Even though I have a brand new computer that far exceeds the requirements, the program was overwhelmed with unnecessary data. Try deleting unused old data.
