Please reupload all files. Looks to me like you have a mix and match of old and new files.
To ensure you upload everything unzip the whole build and only delete the install and config files and upload photopost to your site. Make sure any upgrades have been ran and you will be fine.
Redeclare errors are always a result of mixing old and new files as in example say in vb3.php we move a function to pp-inc.php and you dont upload a new vb3.php file then that function exists twice which means you will get an error. Also please print full errors also when posting because it would have been nice to know what script was reporting the fatal error.
No need to say sorry just reminding you of this thread and its topic. It is hard enough to keep things straight in threads with people bouncing in on them all the time let alone topics changing Feel free to discuss your blurry thumbnails in that specific thread. My uniform thumbnails look fine dont they?
