I'm looking for Xiexe's XSFur shader v1.2.2 - does anyone have it?

I've pissed away a bunch of time trying to get it to work correctly on my map (it's not baking light correctly and thus constantly looks like shit). Xiexe himself has been little help saying that there's a checkbox (there isn't) and then saying 'maybe i fixed it, I need to re-do the shader' which also doesn't help me. Apparently you can't even download old version of the shader on Booth so even buying it isn't the solution. 

I really need this feature and I'm sick of running in circles. 1.2.2 is specifically the version that he added the lightmapping feature. Does anyone here have it?
