Well, what you are writin is interesting.
I installed the whole thing in a XP bottle with crossover 11.3.0. Will try to do the whole thing in a vista bottle too (maybe that will help with the "outdated driver" problem).
I found that I had to run the game in a windowed mode (wine cfr) with a simulated desktop that needed to be bigger than 1024 x 768 (as that is the default resolution of the game). A 1600 x 900 would do.
I also used the "run" command within the applications menu to add the "-doublebuffer" tag behind the .exe file.
Additionally you have to install DirectX 9 via the crossover installer. Also I tried getting the videos to run via Flash Player but that didn´t work. Maybe the Windows Media Player would help?
There is another very strange thing I found. When typing in your Username, the field where you type is already filled with some chars, so you have to delete there first. I guess that this was your login problem. So click on the username field, delete the whole content and than type in your username (I can´t see the username field unless I click on it). Do the same with the password. Then the login should work and you should reach the character creation screen.
hope i can help. Tragically I don't know enough about the regedit (maybe there is a way to disable some of the shader and lightning effects via regedit so the graphic gliches could be rectified).
I have to be quick now, my trial account will be running out in a day or two. 😉
