Stange error in REST1.3

Dear REST authors,

I'm completely new to REST program.
There is no problem in preprocessing of my resting EPI data (slice timing, realign, normalization, smoothing) using spm5.
However, when I run the REST1.3(latest version) and detrend, the following error message comes

Read 3D EPI functional images: "D:\RestingMRI_test\final".Warning: In the directory "D:\SPM_related\SPM5\spm5_2009\spm5", file2mat.mexw32 now shadows file2mat.dll.
 Please see the MATLAB 7.1 Release Notes.

How can I solve this?
I use WinXP professional(SP3) dekstop (quadcore CPU, 4G RAM), matlab 2008b, and latest version of spm5.
Is this a problem of compatibility (matlab version vs REST1.3) or a bug?
My another computer (laptop, Mac OS X, matlab 2008b) works pretty fine with REST1.3-FC analysis.
Any hints or comments on my problem would be greatly appreciated.
Thanks you in advance for your kindness.

Best Wishes,
