HELP - Can't make my level editor work.

[totaltrplayer]

As you can see, I'm a newbie in level editing, mainly because I haven't been able to properly install the editor and making it work.
Let me explain my problem more thoroughly:
I have a Celeron 500 MHZ, WITHOUT 3D Acceleration Grapic Card (this might be the problem), and after installing the editor and runing it, the main screen of the room editor loads, you know, buttons at the left and the bottom, texture window at the right, and window for showing rooms in the top of the middle of the screen. The problem is that once this screen is loaded, two things happen: firstly, the window for showing rooms appears completely blank, although I have being told something should appear on it. And secondly and most important, at that point my PC crashes, and not even the CTRL+ALT+DEL combination will work. I have to reset the computer then.

Can someone help me? I guess a 3D Acceleration Graphic Card might be needed, but if I'm wrong, and you can provide any other solution, please don't hesitate to do so, either here or e-mailing me. And if you need additional information for solving the matter, tell me and I'll explain whatever you need.
By the way, the TR4 levels and the edited levels work fine without the graphic card, if that helps.

I'm sorry to tell you this but i you haven't enough space it does the same thing..
You don't really need a card because i don't have a card and it works fine.
But if you see that the screen is white close the program and try it again may be that helps.

also, are you running at 1024/768 @ 16bit screen resolution ?

[totaltrplayer]

Thank you two very much, but I'm using the proper resolution, and I have enough space.
However, it's a relief to hear it is likely not a problem of graphic cards, because I will not have to buy one.
And no, after running the program, I can't close it and run it again, just because at that time the computer has already crashed. :(

Maybe the color is the problem.
Or else if you have a copied cd, the complete information isn't on your computer.
I'm sorry but i'm really running out of solutions. :confused:

[totaltrplayer]

Well, I'll try as much as I can, and if I still don't find the way to get it working, I'll come here again.
I have the computer set to the appropriate resolution and 16 bit colour, and, if that helps, I have all the level editor files copied in my hard drive, but I don't have the CD (someone I know installed it on my PC)
Well, thanks for your help, and see you later.
Any new ideas will be welcomed
