MATLAB: Do I receive an error when trying to import a MAT file in MATLAB 7.0 (R14)

7.0corruptfileimportmatMATLABr14

When I try to run the commands :
clear;
v6file='original';
v7file='new';
load(v6file);
save(v7file,'a','b','c','d'); 
load(v7file);
where original.mat is a MAT-file created in MATLAB 6.5 ( R13).
I get the error:
 ??? Error using ==> load
 Unable to read MAT-file C:\MATLAB7\work\new.mat
 File may be corrupt.
Even when I save the variables without Unicode, using the command:
save(v7file,'a','b','c','d','-nounicode'); 
load(v7file)
I receive the same error.

This bug has been fixed in Release 2006a (R2006a). For previous product releases, read below for any possible workarounds:
This bug has been fixed for Release 14 SP1 (R14SP1). For previous releases, please read below for any possible workarounds:
This has been verified as a bug in MATLAB 7.0 (R14) in the way that it handles the loading of MAT files.
Currently to work around this issue, use the '-v6' option to save the MAT file in a MATLAB 6.5 (R13) compatible version:
v6file='original';
v7file='new';
load(v6file);
save(v7file,'a','b','c','d','-v6'); 
% The following line should be executed from MATLAB 6.5 (R13)
load(v7file)
