My 30day trial period for win4utomation just expired. Any ideas on how can I make it to work again for another 30 ? I've uninstalled it with revo, manually searched and deleted some registry entries related to the software, restarted PC, changed MAC address installed it again but still no luck. I keep getting the "Evaluation period expired" message ? Where and what kind of files should I look for to delete in order to make it work again ?
