Just downloaded the update today, and I'm getting the same error as Nameless. Please update the zip.
Otherwise, this file is amazing! I had now idea that the sweat function was connected to her breathing counter. Now that I can change that, I can fuck the model and have her sweat while doing so. Great Mod Stuntcock! :)
So you might have downloaded a file which was labeled as "1.1" but which was actually just the 1.0 version of the mod. If you re-download the mod then you'll see that the current version then is also labeled "1.1" ... but it's actually the correct file (and shouldn't generate any errors).
And if it turns out that I've screwed up the file contents *again*, then there's always the option for you to manually compile the *.as source file :)
