[Plugin: Slideshow Gallery Pro] Upgrade Full Edition

Hiya. I donated to obtain the full version and didn’t receive the full plugin by email, but just 6 files in a zip (pro folder with 3 caption php files, custom sizing php and 2 more). Are these supposed to supplement those from the free version and if so, where are they supposed to be placed? I’ve followed the instructions and so far nothing happens.

Thanks!
