Is there anyone else around you who can pick up 2A North that you could plug into. You could do the <switch off> <switch on> routine there and upgrade the software? If not then on your next visit to UK take your box as part of your luggage and upgrade in UK.
Its worth having a look at Satcodx web site to see which of the SKY channels (apart from EPG stuff) are on 2A North.
Guessing from channels that I'm still having a few troubles with in Alexandria (i.e. losing signal during some times of the day) I'd think, if you can't get the EPG update then you may struggle to pick up
Sky Box Office / Movie Max / Movie Premier
Nat Geographic
Channel Four
Grenada Plus
Men & Motors
Still at least SKY Sport comes off another beam.
The other answer is to upgrade you other hardware (bigger dish, etc, etc) which could let you upgrade to the right version and increase your viewing options.
That's how I upgraded my EPG software (dirty great 2.4m windmill on the roof)
Cheers
