Virtuoso 6.1.5 warnings issues

I need some help if possible on the following issue:

*WARNING* (reader): string at line 1 was not terminated on EOF, '"' added at line 2 of string "...)"

I made a lot of search on google unfortunately without success.

Thank you in advance.

Note: The complete Log is given below.
