TestComplete 10.60 problems experienced

A few days ago I updated from TC 10.40 to 10.60.

While running tests I experienced the following errors:

TestComplete just closes without notice...

Multiple experiences of the issue while executing this code (partial code):

obj = objIFrameContent.FindAllChildren(new Array("objectIdentifier", "ObjectType"), new Array("statusimg_0", "Image"), 20);
obj = (new VBArray(obj)).toArray();
obj = obj.reverse(); 
if (obj.length > 0)
Log.Message(obj.length);
}

(it is supposed to return thousands of results, and it does, when TC doesn't just close...)

Besides that I got the following error with IE, several times:

Both of the situations described started ocurring after 10.60 instalation. 

My IE version is 11.0.16.

Thanks in advance!
