troubleshooting

Hi all, long time player, I've recently got an oldies x86 PC using XP and am installing all my favs on it. When I run it I get the error online.exe is not a valid Win32 application, I can still launch the game via PsoBB.exe, however it says its missing bcrypt.dll and only says "Server full"...

I was having problems with my game crashing during quests, looked through the forums for some solutions. I ended up trying to run the .reg file as suggested in some of the threads. When I went to play again to see if I fixed my problem, I ran into a couple more... The Dotum font I installed...

ive got everything installed and i changed the compatibility settings to windows xp and admin start up but when i hit start it flashes a command screen for a sec then nothing. anybody know how to fix it?

UPDATE #4: Less than a day before I bricked it again. The game was working beautifully but ever since the CrU update I drop connection on wired Ethernet every few minutes for a split second (not even long enough to get a triangle error), that would cause kick from the server. Alt tabbed out...
