GuitarPro V1 and V2

[jjvb]

Program Name: GuitarPro
Website: http://www.guitar-pro.com/
Current version:5.2
Desired versions: Any Version prior v2.21, notably version 1.0
Description: Guitar Pro is a multitrack tablature editor for guitar, banjo and bass.

I'm actual writing importfilters for a new notation program and I need old versions to generate sample-files to check the filters. What I already have, is

Guitar-Pro V2.21 (Writing FICHIER GUITAR PRO v2.21)
Guitar-Pro V3.00 (Writing FICHIER GUITAR PRO v3.00, exporting FICHIER GUITAR PRO v2.21)
Guitar-Pro V4.10 (Writing FICHIER GUITAR PRO v4.06, exporting FICHIER GUITAR PRO v3.00)
Guitar-Pro V5.2 (Writing FICHIER GUITAR PRO v5.10, exporting FICHIER GUITAR PRO v4.06)

(the last two i have bought, others are shareware-demos)

Now I'd need these very first versions, v1, v1.04 and so on to check, if there are any differences in the file formats.

Thanks for any help
