Hi,

I suggest you first simplify the expression you used then restrict the  
range over which you are plotting initially.

Plot3D[(10 E^(2 (x^2 + y^2)) (x - y))/(1 + x^2 + y^2), {x, -1, 1}, {y,  
-1, 1}]

Works fine.

I also plotted your original expression on my system OK but it seem to  
be not very useful to do so.

There are an infinite number of ways to get your system and  
Mathematica to fail, the fun is building up sensible problems that  
have solutions you can use.
