When a player logs in to the server, it immediately crashes.

I struggle reading the report. Can anyone help me?

Possibly a problem with PlayerAPI. Did you install it AFTER forge? Also, update to hotfix 18 because 17 had the textures broken.

I've got the exact same problem. Installed Forge (from the TFC wiki) and this version of PlayerAPI http://dl.dropbox.com/u/41082508/Minecraft/Modding/Player%20API/MC%201.5.1%20-%20Player%20API%20universal%201.5.zip

I've followed the wiki instruction which consist of copying Forge BEFORE PlayerAPI inside the jar. I did not run the jar before end, nor in between copying the files. I'm running the hotfix version.
