There are some updates on the Tally Licensing server due to which most of ERP9 licenses are getting into educational mode.
To resolve please follow one of the following methods.
Change the system date to one day ahead i.e. 1st March 2012. Reactivate the license (F12-Licensing->Reactivate License). Then continue working with this date and license for the entire day. The date can be restored back to normal the next day.
Download the latest release Tally.ERP 9 Release 3.31 from our website www.tallysolutions.com. Reactivate the license(F12-Licensing->Reactivate License). Then continue working with the latest release.
You will need your admin id and password for reactivation. In case you have forgotten the password you can simply reset it by pressing F5 OR clicking Reset Password link in top right corner, which will send you an email to reset your password
