The links in my sig will guide you through everything you need to know and provide the resources you'll need.
Be patient, be carefull and you will have a trouble-free rockin' great time with the amazing improvements to the game.
FIRST - you will need the RBII to 3D upgrade,you'll see it as you travel through the links below.
SECOND - You will need the SERVER patches (1.0.7.7, 1.0.7.8)IF you intend to fly on-line.
You will want to have multiple installs to keep Single Player UOP's and Multi Player separate.
I recommend adding everything you'll need (like the UPGRADE to 3D, CM11, copy of the VIDEO folder from the CD to the RB3D/DATA folder,even terrains, etc) then RE-NAME it,make a COPY of the whole shebang (before adding any major UOP's)and ZIP the copy for future use.
You cannot D/L FCJ - $28 will get it, look here:
http://www.plgrafix.com/ Hell's Angels SuperPatch (HASP)is an easy,one-shot total planes upgrade,terrains are your choice but the OTE/PL combo offered at the site as "default" is excellent. You can switch out different terrains as you like.
You can get everything you need for the game from the HA site.
The Western Front Patch (WFP) requires frequent updating of your Campaigns using CM11 and offers over 100 planes to fly, including recons and bombers!
You can get the GLIDE wrappers at Polovski's site:
http://people.delphiforums.com/Polovski/ dgVoodoo is now universally recognized as the best, especially for ATI but you may also want to try the OGL version for your vid card and decide for yourself which is best. Pay close attention to the SETTINGS requirements for each
The NUMBER ONE rule, I guess for RB3D is to run the game at a DIFFERENT resolution than your Desktop.
You're using WinXP so you won't have sound in the game without one of the "fixes" offered - I recommend the FCJ-CP (Control Panel), a stand-alone program that includes the XP fix.
Well, welcome back and prepare to be amazed!
It's always best to ask if you're unsure of anything before mucking up your game!!
