Support has gone Silent

[Camm29]

Recently I purchased an upgrade just to allow installation of 2.7.2.
2.7.2 fails to install on Windows 98 , ME and 2000 and via Support Ticket
RunRev agreed this has been a problem.

It may be put right in 2.7.3

So now i have purchased an upgrade ( No i don't expect 1000 new version's per year ! ) but i expect to get one working.

I need 2.7.2 to work on Windows 98 ,ME , 2000 

I questioned value for money in this situation and now the Support Team have gone SILENT.

Regards
Camm
