i have tried everything from simple reboots, to complete system refreshes, to removing/deleting the while .minecraft folder. i have tried versions like forge, and litemod as well as the official versions. it always crashes and in the launcher says the following. the strangest thing about this is, the error goes away in a day, but after a few re logins, it stops working. i always check xpaw.ru/mcstatus and it always shows that sessions go down for 3 minutes max everytime i try this... im not sure wha this is, but it has happened 3 times consecutively.
