Amazon/Optimal Product Finder

I have a program called "Optimal Product Finder" and it seems to not be working. None of the subcategories are working at all and when I try to do just a general search it says internal error. I would like to have this program working, so if anyone can get this going, please let me know. I am looking for someone who knows about fixing this! I want this program back up and running, so please contact me ONLY if you can fix this! It could be a quick fix or it could be a pain, I don't really know. It was working a couple of days ago and then it just stopped working. Get it working for me and I will gladly pay, as I need this to be done ASAP! This is the second time I am posting this. If you do not know how to fix this program, don't waste my time. I am looking for someone who can have this done and fixed!
