G Force program box firmware

[Simion Wabs]

I have acquired a secondhand 1s GForce Esc with program box and wanted to upgrade the firmware to the latest version to adjust stage 1&2 punch levels. The only option I can find on the web is for v2.08, but oddly, the only available download is for v2.07 on the GForce website. The issue I have is that the program box freezes when connected to the pic and the software doesn't recognise the program box. I have connected the esc as per manual instructions but the software doesn't recognise the esc.
Long story short, since connecting the esc to the PC I no longer have the 'turn off' function by holding the brake for 8seconds. The stage 1&2 punch max setting is "very strong" unlike other progboxes stating "30".
Any link to the latest firmware would be appreciated.
Thanks
