That indicates an asm problem. You likely have a loose asm_pc or str2_pc file conflicting with the mod. A good first step would be to delete all .str2_pc and asm_pc files from your install folder where the srtt exe is. It's likely one of these files that is conflicting. Any time you have mods that use the same asm files then you must update that asm using the command line tools, otherwise stuff like this happens. If you stick with GoS though, everything get built dynamically based on what options you select.
You can also move over the mod cleanup batch file to your install folder that is included with GoS and run it. Then build a new patch file and give it a try.
The other possibility that could cause this would be that you are not running the legal Steam version of the game. All scripting mods will break the game otherwise. (You do own SRTT though since I just looked at your linked Steam profile.)
