Memory Map licence meltdown

Hi all.
I have been using the old free memory map with the old EOtopo maps on my Android 2.2, 7" phone casually for years as my main bush nav. system. It has happily done what I wanted within its limitations. I last used it "in anger" on Nov 11th, all fine. That is until yesterday.

I have been ignoring the new updates because, besides having to pay for the new maps I have to update my phone as well.

I was starting to think about some new trips in S.Aust. and perhaps the Victorian High country when I noticed that some of the maps needed downloading from the internet. (I thought that they were all done). I turned on the wifi and there was no downloading going on. Tried a few times - nothing doing, then Memory Map wanted me to log in with user name and password! I can't remember it ever doing that. I logged in, and it wants me to buy HEMA reg.4 GDTracks.
"Activation rights: In your account:none."
"Needed now: 1 device".

Doesn't sound good!
I can't get out of that screen so I "Buy". (It won't work with my phone though).
It asks for $100, I don't want the maps!
I go to "Need Help" - none of the need help "License Management" is working consistently. Just tried again. I "have to purchase an up-to-date license to use a new version of the software"

Any ideas apart from spending min $250?
I glad it didn't happen on our last trip since I was tour leader.
Thanks BruceK
