Do I need Black Knight to use this 'Mech Pak?
No, the 'Mech Paks will work for you whether or not you
have Black Knight.
I heard that there's a patch that I can get that will let me
play people with the 'Mech Paks.
That's true. If you go to Mechwarrior4.com
you can get Point Release #3 for MechWarrior 4 Veneance or Black
Knight. Be sure to get the one that is appropriate for your setup.
Do I need to get this patch if I already have the 'Mech Pak?
No, the 'Mech Pak already has this patch as part of the install
process. If you have the Pak, you have the patch.
I tried the patch and I get ERROR 0036.
There are a number of "unofficial" patches for MW4 out
there. If you have installed any of them then the patch is not going
to function properly. The best thing you can do is to reinstall
MW4:V, then patch number 2, (and Black Knight if you have it) and
then install the 'Mech Pak.
Can any of the older 'Mechs use the new equipment?
Yes, the 'Mech Paks updated some of the 'Mechs from the previous
releases so that they could use the new tech.
