problem with mamba 1.38 beta, and castle bad service

[TheMonster]

the old version on the the controller has been deleted and I can not install it again.
And the castle man told me I'm stuck with version 1.38 beta.

the firmware updates are directly from castle, and HPI have nothing to do with it...every mamba update from castle, hpi re-brand mamba get the same uptade as well automatically.


as in my first post, i quote a paragraphs from castle site:
"We thoroughly test software updates before we release them but there is no way we can test every possible system configuration.
A beta release comes with a questionnaire and several follow up e-mails so we can get feedback from beta testers on how the software performs.
With this feedback we can fix bugs or other problems before the software in installed on our production ESC’S.
If you are curious about beta software but are leery of becoming a tester, rest assured, all beta releases have the ability to be turned back into the last stable release version."


that means that is I upgrade to beta and want to go back I will be able to do it...
I try to reverse to the older version with no succeed, and the man from castle ignore what their site says and told me I cant go back anymore because the old firmware already deleted from the ESC.
