We imported a backup from our accountant into our sage 2009 without realising it was from Sage 2010. We now cant open our Sage 2009 as it will no longer get past sign in - just says 'This data was last used with a later version of Sage Accounts. You must update this version of Sage Accounts before accessing the data.'
A work around suggested before we knew this was the cause of the problem of saving the demodata into the accdata didnt work for some reason - i still get the same message. might be that i did this wrong so please tell me the correct way to do this.
Any ideas much appreciated.
