i am also having this problem i can't seem to figure it out

Same here, if anyone can help on this it would be great

same here, using windows 7 64bit for the client machine, the server is a Linux host, re-installed the launcher twice, upgraded to java 7 twice (first time i let it auto update, then i made sure to get the the 64bit version specifically) reset the server files twice, nothing fixes it, and editing the railcraft.cfg file doesnt help

I changed the build version on m clien and this seemed to work, but when I changed back I forgot wich one but just tr different ones and it might work.
