Need link to C16S firmware

Can you provide a link or attachment to the most current firmware for the C16S?  I used the 'Smart' upgrade tool, which isn't very smart as it appears to have uploaded the wrong firmware for my camera - something I saw happen in a few other posts here.

I can tell because the camera is now blurry and some of the features in the setup section are missing.

The firmware showing on the web UI is:

Firmware Version          48.53.203.95
Web UI Version                  CH203.1.1.20

I still have access in the Web UI to upgrade the fw manually so all I need is the files.

Thank you.

UPDATE:

No longer needed - the person on eBay that I bought the cam from got the file for me.  Please have your engineers remove the "Smart Upgrade Tool" located at http://www.eye4.so/download/ - not only is it not smart, it uploaded the wrong model firmware to my C16S as well as DOWNGRADING the firmware on two other Vstarcams in my network.  Fortunately I was able to upgrade the other two using the Eye4 Mobile software and like I said, the vendor gave me the correct file for the C16S which I upgraded via the web interface.

PLEASE TAKE DOWN OR FIX THE "SMART UPGRADE TOOL" SO THAT OTHERS DON'T HAVE THE SAME PROBLEM.  It is not the first post I saw referencing issues with that software!

Dear Sir/Madam,
