If I read all those problems, I would suggest to get Sendlog on board. Make a sendlog after the start and after an error.

I had severe problems with my eDGe in the beginning and I was spamming Technical Support with sendlog-files. It did in fact helped them by finding bugs and to help me getting a working eDGe again.

just a thought...

at least it gives me enough to think about before I make to step downloading Ermine.
