Re: Advanced Machines - No such Item
Sorry for the double post, but I found out the problem.
For some reason when tekkit was installed on the server, [2]AdvancedMachines_3.6_bukkit.zip was never added to the mods folder. So I re-downloaded the server files and manually added it into the mods folder. After a server restart everything *appears* to be working fine. I was able to spawn in the blocks that previously I was not able to create.
Thank you everyone who helped, and pointed me in the right direction.
