Hi Hermosil,
If you could be so kind as to use the attachment manager and upload MP3 files to the site and not HECI files as most folks won't be able to open those, thus you won't get much in the way of any responses.
At this stage I can't see them and as such I can't help you out, but in saying that it seems as though the machine you have had donated to you has served a very hard life and will take quite a bit of money to get back into proper working order.
Also am I correct in saying that you are using a Mac at your end ?
Cheers,
BB.
