problem with mamba 1.38 beta, and castle bad service

[TheMonster]

so what am I supposed to do now ?
can you maybe try to send me the old firmware ? and I will install with castle link ?
please try to help my without sending the ESC to you in US... because I can't.

EDIT:

I just got into castle site and saw that there is an update firmware for MMP !!! 1.39 (I have 1.38)

castle site don't tell what bug fix this version fix. I'm afraid to try update blindly without knowing the bug fixes..
Thomas Porfert , can you please check and tell me what bug fixes are exists in 1.39 beta ???
and what do you suggest ? update to 1.39 ?

remainder for 1.38 problems:
1. The car lost power, and Punch ... acting very strange and took a long time to accelerate. The car did not have Punch power.
2. stuttered The vehicle .. like the Cut Off is approaching (batteries were charged)
3. Random vehicle brakes every 30 seconds or so
4. The motor started making strange noises and sounds like it opposes itself
5. The ESC stopped to get a response from the remote for a few seconds every minute or so ... (after 2 seconds I managed to control it again)
