PHP Motion dead

Well I successfully started a new PHP motion site. Which worked for two days and then slowly stopped working. No excuse as to why videos will not upload any more. No excuse why MP3 files won't upload ever. And I bought the template which is now tied to that domain name. I've sent multiple requests for help and that you seem to know what is wrong. I'm going to try another video upload program just to see if it works on their website. It is just amazing how much money can be wasted trying to set up new websites.
