I am not able to run after I've installed MF3.6. Now it will not let me uninstall the program.

Question

Time Warner told me that because I was running 3 browsers I had a "conflict". I had Mozilla, Google Chrome, and Internet Explorer8. We had a poweroutage on cable: both tv and computer (Time Warner's problem). When power came back I could not open my Mozilla Firefox, the other browsers were working. This problem began approximately on Jan 28, 2011. I had the older version of Firefox on Jan. 28th. I was not able to uninstall this from my computer without the help from the tech at Time Warner. We then installed the newer version 3.6. Removed Google Chrome. Again I could not get 3.6 to open. Time Warner told me to contact the manufacturer because "something was afecting my registry".
I contacted ZT, through the Safe Mode we uninstalled 3.6 and installed 3.6. Again, it does not open . I tried to uninstall the progam again and the same message appears: that it is in the process of uninstalling or changing, but it does not start the process of uninstalling. ZT told me to contact Mozilla Firefox.
I have been using Mozilla Firefox for years and would like to continue-
please help me,

Make sure you take package structure into account.
If you have say
package testing.things;
public class Test
    public static void main(String[] args)
        System.out.println("World Hello");
}in file Test.java, you compile it with (assuming your current working directory is at the folder in which the source file is located).
javac -d . Test.javaand run it with
java testing.things.TestThe -d . option creates the output at the current directory (with a folder structure matching your package structure).
