Can not make it work ! No support – PDF Editor with Word Processor & Sketch pad Review

I paid for what I wished was the answer to my needs. I downloaded the app and when I launched it I tried to load my files which are stored in my iCloud with no success. I tried go get the on-line help and of course it gives a 404 error - web site not found !! App appears to sound good but functionality is not there nor the support. Un- happy user Where is the support and what is way one gets help with a product that does not seem to do as advertised ???
