Why is geosoftread not working?

I keep getting the following error message when I try to use the function geosoftread :

Error in geosoftread 
(line 36) bioinfochecknargin(nargin,1,mfilename);

I tried redownloading the toolbox for bioinformatics, changed the soft file location, etc. and its still giving me that message. What do I do?

Please show the entire error message, everything in red.

[Mohannad Abboushi]

Undefined function 'bioinfochecknargin' for input arguments of type 'double'.

Error in geosoftread (line 36) bioinfochecknargin(nargin,1,mfilename);

Error in ca04_fun1 (line 32) GEOSOFTData = geosoftread(soft_file);

Please show the output of the following:

which -all bioinfochecknargin
ls(fullfile(toolboxdir('bioinfo'),'bioinfo','bioinfochecknargin.m'))

If the file exists both ways then look on the first of those two lines and see if it says "No license available"

It says it has no license available, what do I do since i purchased matlab and downloaded this toolbox?
