I'm having problems getting the game to work right. I get this:

When I try to get to the login screen.
When I try to update the game, I get this message:

I thought a saw a thread adressing something similar to this, but I tried looking around the forums and could not find it again. I'm sorry if this is a known error already and I'm making an unnecessary post.
my system is like this:
Windows XP professional x64 edition [duel core]
AMD Athlon 64 X2 Duel graphics cards
Core Processor 4400+
2.21 GHz 1.00 GB of RAM
I've had problems in the past because of the duel core and duel graphics cards, but after a lot of research I got EverQuest 2 to work without any problems, and Elder Scrolls Oblivion.
I downloaded the patch, but because I have no way of purchasing winzip right now, I had to use a free unzipper [funzip] and move the patch folder manually into the PlaneShift folder, but I'm not sure if I did it right. I just copy and pasted it into the PlaneShift folder, I didn't override anything [I don't know what to override]. I've tried rebooting and re-installing. Any help is appreciated, thanks!
