What Happened to My Password Manager

I recently installed a new router & modem. Now I can't find my password manager on my desktop. Don't know if there is any corolation. When I try to open the program from the programs list nothing happens, and I get an error message, "Symantec Intergrator has encountered a problem and needs to close. We are sorry for the inconveience."

 

My major concern, beyond the inconvenience, is that my data, (passwords) is not secure.

 

The PM has been running as a stand-alone program for years, and has worked flawlessly on my Win XP machine for years.

 

Thanks
