Need help on a Philips PCRW804 problem

[cachirro]

Hi all!

I have a Philips PCRW804 wich burned ok, then i downloaded Philips Flashtool and updated the firmware, since then i can't burn cds, it burns with no errors, but when i try to use the cd nothing works, apparently all files are there, but it shows errors like "file not found" when trying to use on file, in resume, the cd doesn't works.

I don't know if the problem is that i've updated the firmware, anyone knows?

Wich is the original version of the firmware of my burner?

I appreciate all help on this, thank you all.
