Thanks, I worked it out though. First test by uninstalling HDMod worked so I looked into the thread, someone had the exact same problem. Turns out I needed to rename a strings folder. Both FMs now work using DarkLoader! :)
EDIT: So whoever runs into this again, this problem is not mission-specific. All FMs are probably affected and it is due to Gecko's HD Mod for Thief II (ver. 0.9.5, so still in beta and expected).
SOLUTION: Open the HDMOD folder and rename the folder called "strings" to "strings_". That should solve the problem!
