Unhandled Error - Step by Step
1. In Windows 8, 8.1 or 10, click on the Start Menu button
This is the icon with four panes in perspective

2. Type the word "Run"
You should see a panel fly out that looks something like this:

3. Click on the greyed bar that says "Run"
You should now see a small dialog:

6. In the same way, expand Software and Bell-Lingo

7. Click on the sub-key Bell-Lingo Français

If the value of Window State is 1, we need to change it to 2. (If it is already 2 or 0, please contact Bell-Lingo for further advice.)
8. Right click on the entry, Window State, and select Modify ... from the pop-up menu
If you're not sure what we mean by "right click", this means hover the cursor over the entry, Window State, and click on the right mouse button.
Doing this will open one more dialog, offering you the chance to change the value:

9. Change the value to 2 and then click on OK
10. Close the Registry Editor and restart Let's Begin
Now that you've made that change, the application should work once more. Contact Bell-Lingo, if it doesn't.
