You join the Blitz Matrix/CS Ladder by joining the club.
https://www.theblitz.club/message_boards...n=register There is no "ladder" at Matrix.
You mentioned that you played a game and I think you were on the ladder here? If so, you must ask one of the CS Ladder Commanders or club super-moderators to reactivate your account.
Or, you need to follow the above line guided by this rule:
#2 Joining and Boot Camp
When joining the Blitz, a player will fill out the forms required to identifity which ladders they will join and what wargames they have available to game with. A member may have only one club "Member Page". You may be on multiple ladders but, you may have only one account.
Players have several options of Armies and pictures to join based on which ladder they've joined. At this time, a player can have up to three different Armies and pictures based on the following: 1) the American Civil War Ladder; 2) the Napoleonic Ladder; and 3) the remaining ladders.
Once a player completes the joining process, they are placed in the Boot Camp until they complete a game. This is to deal with the problem of players joining, but never completing a game. This is our method of preventing our ladders from becoming overcrowded with non-gaming individuals.
After being placed in boot camp, a player has 3 months to complete the first game on the ladder(s) to which a player belongs. If a player does not complete a game during this time that player is subject to removal. A player failing to complete a game within the specified time period is notified by the Ladder Commander. Arrangements for additional time are possible if the player wants to remain on the ladder. It is the Ladder Commander's responsibility to update and purge the ladder's bootcamp. It is the players responsibility to notify the Commander if more time is needed to complete a game.
A player is removed from the boot camp by successfully reporting a game completion or failing to respond to the Ladder Commander's notification.

If you were a ladder member, all you need is to be made active again and have a game reported against you.
