Thanks- Had a similar but different problem today. I used the stamp identifier to find a plate block of 30c cardinal stamps. In the first attempt, I put '30c' in the denomination field, and 'cardinal' in the text search field, but got nothing back. When I tried just the '30c' in the denomination field, I got several returned stamps, but not the one I was seeking. When I put just 'Cardinal' in the text search field, I got several stamps returned, but not the cardinal stamp I was seeking. I finally got out my Scotts catalog, and found the stamp, Scott# 2480 30c Cardinal.... I did a seach with '2480' in the text search field, and nothing was returned. The stamp is in the programs catalog, but is as if the databases are not linking properly. I disabled the antivirus and firewall during the last insall, to no avail. 'If it might help, I am currently running the program on an HP Probook using Windows 7 x64, an Intel I5, 16gbRAM, and 500Gb hard drive. I keep feeling I've overlooked something, but I went by the manual when I installed it. Thanks.
