Need help with Creative CDRW 6424
 

Can anyone help me?

I have a Creative CDRW 6.4.24 and it's not working anymore.
About a month ago it started writing CDs with errors and I ended up with plenty of coasters, and now it won't right at all.
I've tried Nero, NTI, Prassi, CloneCD and none work. I've tried reinstalling it and I'm pretty sure I have the latest drivers and Firmware.
Still it won't work. Sometimes it will be about to write a CD and then it will sound as though it is trying to read the same part again and again, freezing up the pc.
Other times I received an error message mentioning something like "keysequence3".

If anyone has any idea of what is wrong, please reply.

Thanks
