Starting last week this problem is solved. Songsterr now supports all the major Guitar Pro formats, so you can submit tabs without worrying about their versions.

New Feature: Support of Guitar Pro 3 and 5 Formats
Till now the only supported format of submitted tabs was Guitar Pro 4. This was really a show stopper if you wanted to submit a tab in Guitar Pro 3 or 5 format from the net (e.g. from 911tabs.com) but didn't have a Guitar Pro software to convert it to Guitar Pro 4 format.
