This might seem a silly idea but have you tried asking in a support request (if you can) over on the main site to see if they are willing to give you a copy of them ?
Although I would guess its probably unlikely they still have / would want to, the way I see it: There is absolutely no harm at all in asking them, worst case is they say "no!"
It would be possible to do this via a different software, a free one going VB2 > Free > VB3 or VB4 but that's quite messy as you likely know and things like posts could get a bit unformatted not to mention possible password loss etc etc. I'd consider that way the "last sensible DIY method"
