I just Figured that PC composer **** out!!!
i just installed Pc composer 1.0 and i copied that mpapi3.dll to c:\program files\shared\nokia\mpapi and renamed the ncds3.0 mpapi3ps.dll to mpapi3ps_orig.dll and then i renamed the pccomposer1.0 mpapi3.dll to mpapi3ps.dll and i searched registry for the first entry of that dll, and renamed it to mpapi3ps.dll and now both work with no problem!!
i hope those things help you guys out
