first of all I DID NOT MAKE THING IDEA but i fine it helpful so i want to post it to all who cant get it to work. yes i did copy and paste it
okay, first you will need to create two accounts so you can have two versions of CR open at once,
Then you log both of them at the same time.
Then position one of the CR you have open behind the other
The CR panel you have open in the front should be a little farther up on your screen so you can see both start buttons clearly.
Now, just click "start game" on both CR's as quickly as you can.
and Now you should be able to connect using the most recent Version of CR GOOD LUCK
this idea was mention by Elirry in the offical CR forum. all thanks should go to him.
hope this help , it work on my first try so give it a shoot to who ever cant get it to work
