Norton Antivirus blocks the v4 for some reason.

I just got v4b and Norton Antivirus blocked it and said SONAR has removed the file. For v3 this did not happen though and worked just fine, can anyone help?

This is likely due to the method Mike used to download the banner at the bottom of the launcher. Simply go into your settings and add an exception to Norton's checks for MM8BDM.exe.

If that doesn't work, try using DoomSeeker under "create server" to launch sandronum.exe [included with MM8BDM's release zip] with the iwad set to megagame.wad and an additional pwad set to MM8BDM-v4b.pk3.
It should look similar to this:

(click to show/hide)

Then hit "play offline."

Or use ZDoom Launcher, but that program's UI is much more complex.

After using DoomSeeker it now works thank you very much Lego :-D
