It could be the type of internet browser you are using. I would recommend updating your flash program, since both are using the flash chat thingie ma gig. But as for En world ISRP, the site is down. No one can get on it. Unlikely Heroes is probably your best bet.
But make sure that version is compatible with your operating system and browser version. Also make sure your internet settings allow for running flash games.
The Unlikely Heroes chat ( Unlikely Heroes Chat ) is working for most people. Make sure you've first clicked the "register" link. You can't go into chat at all otherwise. And registering at EN World doesn't transfer over to Unlikely Heroes: you need to register separaterly. If you're having problems getting registered at Unlikely Heroes, drop an email to ISRPmagi@gmail.com and let me know.
