I've got it working with the 9r10, thanks. Is there an update that will work higher I can tune my 2011 Sierra with?

After downloading 9r31 using dsdownloader I get message "wait for tool to boot".
Tool indicates installing. Waited for more than an hour but no boot.
Now get "missing or corrupt" when plugging. In.
Tried to download twice.
Old crom was 9r10

Does this mean ready for the trash.
