I have found if I try any version after 10-3-23 that there are files that are scrambled in the demos. I have now tried on 3 different systems and downloaded from 2 different computers. Some directory's have no files in them. The ones that do will not load or run correctly. Seems to be ok on versions before 10-3. I also get lock ups at random times. Using different SD cards is still the same results. Tried from 4 gig to 64 gig cards. Weird....
