Try this to correct your computer security problems if you have normal Windows.

At the top of the page toolbar, click on"Tools"
Click on "Internet Options"
Click on "Security"
Click on "Custom Levels"
Move your security level to "Medium Setting"

Also check your options for Pop-Ups. I don't allow pop-ups but keep that selector on medium also.

By-the-way..... buy a name-brand muzzleloader by Knight, White, Austin-Halleck, Thompson Center, Lyman, Pedersoli,Dixie or Cabelas.
