[GNC] ancient gnucash files not opening

[Bryan Murdock]

I'm using gnucash 3.5, trying to open files from 2002 to about 2005
and for each one it says, "This file/URL appears to be from a newer
version of GnuCash. You must upgrade your version of GnuCash to work
with this data."

Is there any way for me to open these old gnucash files?

Thanks,

Bryan
