Unpacking problem

Tried unpacking Paltalk 5.0.71.494, packed with WWpack32 1.x, used Procdump, but on trying to run the file it wont start.
I found a tut on the net about removing the advertising that loads at startup and shutdown, which was on a slightly earlier version, but they unpacked it successfully with Procdump.
I can find the code to patch in the unpacked version, but the unpacked exe wont run patched or not.
Where do I go from here, I thought this one would be quite straightforward.
Yes, I know it is a pissy chat program, but I only use it to join in on a soccer chatroom for my club in the UK, and those ads are an annoyance.
