BDP s350, Firmware and Bond 50  

Hello, im having an issue with a box set i had recently bought. My bond 50 collection is not playing on my bluray player. i did get an upgrade from a burned cd-r and it had actually looked like it worked for once. but it kept saying that it cant load disc. Any ideas on what i can do? BTW, is there any specific way how i should have burnt the firmware onto the cd? cuz it seemed that it worked but it wasnt the solution. thanks in advance for your help
