Checking your log you are trying to play Dissidia 012 and it should work fine. Same old deal, did you try to follow the instructions here? http://www.emunewz.net/forum/showthread.php?tid=14984
Besides the obvious question, did you try to press run?, it could be an issue with media engine or similar. Also notable that the log mentions "unrecognized file format". You did make it into a .cso/rar/iso file and put it in the UMD browser before attemping to load it up?
