Don't panic yet Jonathan,

It could be the result of a number of things, and even at those numbers ( even though they aren't ideal ) would probably run just fine too. George knows the drill, he will get it up running for a while, and then re-test

There are a lot of good people here to help too .... i'm sure it will be up and running in no time.

Try to focus on the positives, seeing how much you have learnt through all this, and how it will help you when you are in the middle of nowhere, or you come across someone stuck in the middle of nowhere
