Tekkit Server white-screening

[monkeyblaster]

Title: Tekkit Server white-screening

Version: 3.0.3/3.0.4

OS: Windows 7 64-bit

Java Version: Java 1.7.5.0_05

Description of Problem:

My friend and I were playing on my tekkit server before both of us were kicked off via the white-screen. It worked for about 3 days with no problems before this happened. I have already deleted my player. dat file and that did allow me to spawn into the server, but then i none of the blocks were registering. I fixed this by changing the detail distance. I can see now, but it just delayed the length of time until it white- screened instead of solving the problem. Any suggestions on how I can fix this, or barring that, re-set up my server while saving all of the work done in it?

I should note that I am running the server on the same computer that im playing on.
