Well.. You did not answer my question, but since you were using a 1.9 exe and changing to 2.0 didn't work, I can be sure it is not an id limit problem.
Solution:
Make your bigger sprite grids smaller in size. You might have to go through all your sprite grids, redo them, replace the sprites in the smaller squares, and reset the centers, bdys, itrs in the .dat for all the grids you've clipped.

A faster solution is to just get the A-Grid Clipper: http://www.lf-empire.de/forum/showthread.php?tid=8902
It is still going to take a while, specially if you're going to clip the sprites of the whole mod, but it is 1000x faster than if you would do it manually. Just place all your .dat files and sprites in the "input" folder, run the program, wait until it's done, and copy all the new generated .dats and sprites in the "output" folder to your mod.
