Hi All,
 I recently had to download the Evolver Editor program again, because 
my computer crashed. Every time I load setup it gets to the last 
thing it has to load, then a message comes up and says my system 
files are out of date and Windows will now update them, but I need to 
restart to run set up again. I restart and the same thing happens.
   When I click on the Evolver icon it asks me for my name and my 
code. I give the info, it says it accepts it (but the prompt won't 
leave the screen unless I cancel it), but when I use the editor I 
can't save anything because it says I'm still in demo mode.
      Anyone have any suggestions? 
                                  Thanks,
                                                  Swanoid
