Yet another steam error...

[Apex]

One evening I booted up my computer and all of a sudden this error popped up when Steam was loading in the system tray. I manually tried to open Steam and it gave me the same error. I googled for a solution and of all the results I found in English(very few), the solution was to completely reinstall Steam. Anyone have any ideas on a different solution?

Heres a SS of the error with a bit more info.
