help, getting ttsynth serial

[Kristoffer Gustafsson]

Hi.
yesterday my external harddrive crashed.
I lost very very much files, including the ttsynth binaries and the serial number.
Since ttsynth is no longer availbable, I can't buy it again.
but since I've already bought, there must be a way to get my serial number back.
Who shall I contact and ask for help?
I know I could buy voxin, but it seems very hard to install and configure.
