ok, this is wat u do. first, open my computer. then, got to the hard drive u installed d2 lod on (drive c or d) open the diablo 2 file, then look for patch_d2. COPY it and PASTE IT SOMEWHERE SAFE. REMEMBER THE NAME OF THE AREA WHERE U PUT IT!!!!!!!! now, open up the mod file. it should have another patch_d2 in it. i would consider renaming the MOD patch to sumthing like dropmodpatch, or sumthing that has to do with wat it is (cowmodpatch, u get the idea). copy the MOD patch, PASTE into the diablo 2 file, and ur ready!
