Trying todownload a 5.8 meg file.  have 100 gigs of free space.  I download 4.4 mb files, no problem but over 5, I keep getting the errior, not enough space.  What am I doing wrong.????

Are you downloading to the same folder as before?

If a different folder, check permissions on the folder.

I'll try another folder.  I am  administrator so thats not the issue. I have tried to save to an exteral usb drive.  Everything else there is fine, with 300+gigs frees,  a 5.6 mg file should not be a problem.

You may be an Administrator but depending on your version of Windows Tixati may not be running as admin.
