I keep getting an error when advancing to a new year. I opened the clients opening balance from their accountant via trial balance. Everything balance but when I try and start new year I get an error "The sum of your vendor's information does not equal the current balance of account 1300 Computer software . Either your vendors historical information or the opening balance of account 1300 Computer software, or both is incorrect. 

I did not enter any information in the vendor module it came straight from the account so I am at a loss as to how to fix the problem. 

Any help would be great.
