I would like to keep using the MYM launcher, but when trying to access other SF 2.5 servers, missing that pack prevents even joining. Glad its off the server, but out of the client is where its causing issues.
Well, MYM Launcher is adapted for MyM Servers, and Fluid Cows had to be disabled from server because of client crashes. You can see it here.
The MyM Launcher is only meant to be used with our servers. You can add it back your self, but for your information, we removed it because it caused clients to crash, too.
If you go into the modpack folder and remove the ".dis" you will be able to join other servers. Please disable it before rejoining ours thought.
