Hi Luis,
It matters what browser and what version of Foxit you are having problems with the error. You might want to post that to get better advice from the gurus.
You might want to start a google search by filling in what you have inside my parentheses: (Name and Version of your browser), Foxit Reader version (the number here), problems
Something like: Internet Explorer version 9, Foxit Reader 4.2, problems
If not helpful, try uninstalling and reinstalling Foxit.
If not helpful, try uninstalling and installing earlier version of Foxit.
If not helpful, try copying the Registry for Foxit, if same windows version, on a computer that is working correctly without the error, if you have one.
If not helpful, take a vacation. You deserve it.
