Failed to add row / Failed to update row

I have been using accointing for about a year now.

I have not paid for the program yet.

I am no longer able to add or change data. (few weeks now).

Am I sort of ‘locked out’ because I still have not paid?

Every change I make, or line I add, I get messages like: ‘Failed to add row’ and ‘Failed to update row’.

I don’t mind paying, but I need to be sure that the software will work afterwards!
