I decided to remake my C3PO.cfg file (by copying the original out of a fresh copy)
This deleted my CD keys I had used and now I have a few quick questions:

1) the option of "Use CdKey File" has no explanation on how you write a CdKey file or under what file type (.exe/.txt/.mpq/etc...) it should be made.
Guessing based on another site search it should be CdKey.mpq but I have no idea what the format should be (1st line XXXX-XXXX-XXXX-XXXX 2nd line XXXX-XXXX-XXXX-XXXX?)

2) having looked on these forums I was able to figure out that I am limited to 2 CD keys with a "subscription". Is there anyway to increase the limit to say 4 CDKeys (1 enchanter, 1 BOer, 1 Leader/Rusher and 1 Follower/leecher/rushee)?

1). You need to search internet for "how to make diablo 2 cd key file" or something.
Usually the 1st line is for your classic D2 cdkey and the 2nd is for expansion.

2) Just make the payment double.

6. After you launch a D2 instance using C3PO, select D2X2 in gateway selection.

i do that but when press on button battle net i came on rubattle net, and i dont see d2x2 realms what need to do?

It seems some part of your rubattle.net installer or program redirect all other out going server connection to rubattle.net.

Please ask to the rubattle.net community about that, and once you get the answer, please post your self-solution here for the Russian users.
