OK, I fiddled around a bit and my license files definitely aren't working.
I had 100Mhz bandwidth earlier because I was using vendor.bin for a DHO814.
I can make the 'scope into a DHO914 and get 125Mhz/50M, no problem, but the 100Mhz bandwidth is the sweet spot IMHO.
I also tried puting in my original Key.data. The scope upgraded it to RKey.data just like firmware 1.02 but no joy. In DHO800 mode my memory is 25M/10M/5M depending on number of channels.
The memory upgrade option has also disappeared from the "Options" screen.

Have they removed it completely or do we just need a new key generator? I'll leave that in the hands of the hackers...
