try to do this>> right click on tantra-K13 launcher>> properties>>compatibility>>change settings for all users>> check (run this program as an administrator.
then..
if u still get hangup/DC/ERROR dont run ur tantra launcher in administrator or dont make your tantra run in full administrator.... just run it normal and make sure ur Resolution same as u have on ur PC or LAPTOP and also your Option/Spec set it HIGH it will fix 80%
i hope it will help!!
