Hi,
I started using VoxCommando a couple of builds ago and have experienced the same issues since then: Whenever I try to open the Command Tree, the following message appears:
Your command tree is an old version.
Your voicecommands file has been backed up to: voicecommands.bak## (number, in this case 29).
Please save your command tree to update it now.
The issues have been verified on Win7 Ultimate and Home Premium with admin accounts. It seems no matter what I try to do, this message pops up.
