Error messages on exit

Hi there. What do the following messages tell me? How may I fix the problem? Thanks!

First one showed:

...and then this - "exception...", "click OK to terminate the application":

Search the forum for Runtime Error and you will find many discussions. :)

It seems to me you have justg made the search and found there are other threads indeed, actually most of them in the Speccy forums, none that I found with related discussion of possible cause and solution to the problem I am reporting.

Any help still much appreciated.

Another thread you could look at is this
