"svn update" worked today. It detected a conflict since I had already changed the local copy of problemRandomize.pl --- I am glad that I had already downloaded a pdf of Version Control with Subversion (from svnbook.red-bean.com) so that I could learn about "tf" (their file) as my appropriate response.
After your fixes, the problems now load with buttons for both Show Source and Get New Version. Thanks.
problemRandomize --- errors trying to load
