125Khz with "clone protect" flag?

Hi, finally I got a PM3 easy, I know nothing about it, so I started following the article “getting started with Proxmark 3 easy” at this URL :

Getting started with the proxmark3 easy - DT Info - Dangerous Things Forum

things went well till making the build, after some work, everything frose with the message “ccx proxmark3” i waited for half an hour, then I restarted the PC

now, if I type again the command “make clean make -j8 all” as siggested in the article, that’s what it shows … (see picture)

How can I go on? thanks
