Hi! Today i downloaded the master server package and i had to upgrade it to 2015 VS. But now when i build it gives me errors:

These are example lines (they are all almost the same way)

        sprintf(buffer,
            "Actual bytes per second sent         %"PRINTF_64_BIT_MODIFIER"u\n"
            "Actual bytes per second received     %"PRINTF_64_BIT_MODIFIER"u\n"
            "Message bytes per second sent        %"PRINTF_64_BIT_MODIFIER"u\n"
            "Message bytes per second resent      %"PRINTF_64_BIT_MODIFIER"u\n"
            "Message bytes per second queued      %"PRINTF_64_BIT_MODIFIER"u\n"
            "Message bytes per second processed   %"PRINTF_64_BIT_MODIFIER"u\n"
            "Message bytes per second ignored     %"PRINTF_64_BIT_MODIFIER"u\n"
            "Total bytes sent                     %"PRINTF_64_BIT_MODIFIER"u\n"
            "Total bytes received                 %"PRINTF_64_BIT_MODIFIER"u\n"
            "Total message bytes sent             %"PRINTF_64_BIT_MODIFIER"u\n"
            "Total message bytes resent           %"PRINTF_64_BIT_MODIFIER"u\n"
            "Total message bytes queued           %"PRINTF_64_BIT_MODIFIER"u\n"
            "Total message bytes received         %"PRINTF_64_BIT_MODIFIER"u\n"
            "Total message bytes ignored          %"PRINTF_64_BIT_MODIFIER"u\n"

The line under sprintf(buffer,
is marked red. And this is the same everywhere elseā€¦

Thanks for any help!
