Issue in concordance copying and saving the files in SDL 2015

Hello All,
Greetings!
I am having SDL Trados 2015 corporate edition in my office. Some days ago the systems got crashed and I have to reset the licenses on both the systems and had to re-download Trados studio 2015 SR3 version. While working with the same, it has been observed that although the concordance shows 90-95-100% matches; I am not able to copy the same directly using short-cut keys Control 1/2/3 depending upon the serial number of the hints of the concordance search. Can anybody guide me. Also Whenever we press Control S for saving the file the Save As dialogue box gets opened instead of saving the file.

Thanks in advance

Prasann
