Yea the problem isn't from wget it is just one from Mozilla
Ok, used md5sum on 3 files, one is the original copy I have that I used to upload it here, one is downloaded in IE and one is downloaded in Mozilla and here are the results.
That shows that something is going wrong in it.
Now what is being done to it when downloading it etc... I have no clue on but it is changing for some reason. It isn't the file name changing since both are still .tgz files which they should be. BTW that md5sum was done in cygwin.
