Ok I'll try. I already had a 5.5 build (whose most DLLs are v4) and it worked with older style keys. I just happened to see today there was a newer build available (check every *some* months) and that it had a newer style license string attached to it. I haven't yet tried it, but it looked the API and the docs had not changed. Hence my question.
So... I'lll try the new string, passing "unused" for devcode. If that doesn't work, I'll pass immediately previous codes. And if that doesn't work either (which I doubt) I'll come back here.
