While searching through my archived "do someday" files looking for a good Tiger Meet subject, I discovered none of my Model Art files that were purchased directly through the good doctor's website will open any more. Has anyone else encountered this problem? Is it an incompatiblity problem with Adobe Reader 7? I know the files worked at the time I purchased them, and did not require a key/password in order to read them. Any suggestions? I have to admit, considering the expense of those kits, I am pretty thoroughly upset with Model Art at the moment.
