dhtmlx tree ver 5.1 exception thrown and not caught


Hello everyone!
I start working with dhmtlx Tree today. recently I have had very nice experience with Gantt and Grid, thank you.
I’ve downloaded the package from the site and when I try to run any example locally, I’ve got error in the developer’s console of IE11

Exception thrown and not caught File: dhtmlxtree.js, line: 9, col: 31232
Si I can’t see any tree in the region specified.
Could you help me?


Please, make sure that you are using any kind of web server to open the samples.


OK, the problem was in missing xml file.
