Hi, can you search your hard drive for a file called HEADERS.WCD. When found delete it. Does that fix the issue?
If not, can you post a screenshot showing the screen with "1 stamp per country"...it is usually quite helpful.
if not, do you have MICROSOFT ACCESS installed on your computer? If so, can you open the STAMPDATA.MDB file. How many items are listed in the MyCollection table.
if you do not have MICROSOFT ACCESS, please ZIP and email us your STAMPDATA.MDB file.
