playmidi problem in miditoolbox (matlab)

Hi,
I've just overcome the problem of readmidi and writemidi commands with midi2nmat and nmat2midi commands. But there have been the same problem with "playmidi" command. The massage shown in matlab is;

>> playmidi(deneme,145);
Invalid MEX-file 'C:\Program Files\MATLAB\R2013a\toolbox\miditoolbox\t2mf.dll': The specified procedure could not be found.

Error in mft2mf (line 36)
t2mf(ifname,ofname); % mex converter, works in Windows, but see next

Error in playmidi (line 44)
mft2mf(ifn,ofn);

Is there any solution to fix this?
Please help,
Thanks...
