Bracket shooting in v2.1.0

[coosmac]

Just installed v2.1.0
I can only shoot Bracket shooting once.
After that if I try to shoot Bracket shots again there is no response


I use EOS70D

I reinstalled V2.0.0 because of above error.
But now I am getting image transfer error (from my EOS70D to PC)
One image will fail to transfer in about 5~10 shots. I didn't have this problem before installing v2.10 (and uninstalling)

2018-11-08 09:58:23,323 [3]ERROR DCC [(null)] - Transfer error !
System.IO.FileNotFoundException: Could not find file 'C:\Users\Owner\AppData\Local\Temp\tmp4172.tmp'.

Is there something I can do to fix this??? Thank you
