yeah the plugin. what skin are you using? post the gbpvr.exe.log file (found in the gbpvr root directory, ie C:\program files\devnz\gbpvr\gbpvr.exe.log)
you dont have the database file, you need to download mydatabase.mdb from the wiki (my videos page), and the "My Videos" settings in the config app, change the connection string to "mydatabase.mdb" from "videos.mdb" (there will be extra text in the textbox, but you just need to change that bit, if it says videos.mdb, it might say mydatabase.mdb already).
