    I was able to open all 3 xlxm files using LO 3.6.4.3 or 4.0.0.0 
(Beta2) on a 32 bit system with 2 GB RAM. The third one contains at 
least one macro. I do note that LO 3.5.7.2 crashed when trying to open 
the third file. All of these were downloaded from the LibreOffice 
website. I also have LO 3.5.4 from the Ubuntu repositories. It opened 
the first and third files; the latter took a long time to load. I 
guessing that there were a large number of macros that had to be 
disabled as the spreadsheet was loading. (I did not try to open the 
second file with LO from Ubuntu.)
     If the large number of macros in the third file are what is 
causing the problem, then you need to reset the security settings for 
your LO. (Tools -> Options -> LibreOffice -> Security) If you know that 
the macros are safe to run, reset your security settings for files 
coming from this particular location. To do this download the files into 
a special folder that will only contain files for this course. Then 
listed the folder as a trusted source. When you do this, macros will run 
in any file in this folder. Just make sure files in this folder contain 
only macros that are safe to run.
