I have just downloaded the 1.1.18 server from the website, and have it running on a minecrafted.net server
After working out some kinks with tradebooth(see: removed it), we are getting an error when loading the client stating that there is an ID mismatch with: logisticspipes, appliedenergistics, buildcraft|transport.
I have attempted to install newer version of these mods for mc 1.5.2, which is the version that tekkit uses, but it still gives me errors.
