I might sound a bit lame, but this is funny how often we get complaints and how little we get donation...
(I think we should charge for technical assistance, like any software company...)
So where's the donation address? I can only find the addresses of Christian and Christian in ccminer, when compiling your sources. Haven't found it on github either.
Not that this helps you but all devs are listed in nvminer with donation addresses on the help page.
Just thought I'd throw this out there.
