Just set up a new fresh server for this.
It's running on a Linux box with the following
 SourceMod (1.3.6) by AlliedModders LLC
 Accelerator (1.0.1) by Asher Baker (asherkin)
 TF2 Tools (1.3.6) by AlliedModders LLC
 BinTools (1.3.6) by AlliedModders LLC
 SDK Tools (1.3.6) by AlliedModders LLC
When mw_tf2ware.smx is in the plugins folder the server crashes on start up with
error: Failed to open/read local data from file/application
If I take mw_tf2ware.smx out of the plugins folder the server starts fine.
All TF2ware content is present in the correct folders. All files in the server folder are owned by the user that the server runs under.
