Hi presidente. I've done a bit of research via Google. It appears that the loss of scsihlp.vxd shouldn't give any problem unless you have a scsi drive. If you need to, you should be able to replace the file from your Windows cd. I found a reference to almost exactly your error message in a Google translation of an Italian web site, but the advice given was that either a badly connected ide cable or a faulty cd drive was the most likely cause.
