wish I had some answers for you on this but I don't,
unfortunately though, sonar 8.3 is some years old and as well is windows xp.
that operating system will soon be phased out by Microsoft and no further updates made available(if they haven't already phased it out.(I know they said sept of 2012 but they usually go a l little longer.
I totally understand where your at and im sure money is as always the biggest issue.
even the new sonar x2 will not run on windows xp or vista,it wont even install.
I hear where your at though and I wish you my very best.
a word of advise, take it as you'd like though.
don't let technology leave you in the dust.
I don't know the curcumstances as to why your using 8.3(it is a great sonar though)
but getting help is tough :(
well if anything I hope I have given your thread a bump so someone else may have a look and give some reall advise to help you out on your adventures.
my very best to you,sincerly mean that.
