So i was recently looking at writing a keygen or crack for Visual Lint (hxxp://www.riverblade.co.uk/products/visual_lint/index.html), but for the life of me i cant figure out what packer they used!

I've tried PEiD, AT4RE FastScanner and a couple others, but cant find whats being used. Putting it through IDA didn't reveal much useful either. Any ideas?
thanx!
