Problem with DS1102E

Hi i have cloned the project and it opens. But when I conntect to the Oszi it cames a failure:

dsremote_002

As i read here: https://www.eevblog.com/forum/projects/software-tips-and-tricks-for-rigol-ds200040006000-ultravision-dsos/550/ i changed in the mainwindow.cpp

f(!strcmp(str, "DS1102E")) { devparms.channel_cnt = 2;

devparms.bandwidth = 100;

devparms.modelserie = 1;

}

But sadly nothing happens. Any Idea?
