Could not create cabinet file for accountant copy

I am new to SAGE CITY. I have been using Sage pro 2012 since 2012. Every year so far, when it was time to create an accountant's copy to send to my accountant, the program produced the CAB file with no problem. Today I was trying to create it and it goes through the normal process but cannot create the file. I captured the error message and attach it here. The first time I tried it said that the folder : Program files (x86)\Sage simply accounting pro 2012\DATA\ACCOUNTANT  does not exist. I created it manually. Then I rebooted my computer opened Sage and tried again. It asked me if I want to replace the existing Accountant's copy I said yes. It is tyhen that it started the creation of the file and close to the end it gave me the error message. Any help, please?
