This one is simple: file/database formats change. Not all programs -- strike that -- almost no program maintains the whole history of file/database formats for upgrades.
Sometimes you need to have GenealogyProgramPlus v2.3 around together with v4.8, because the file format changed from v2 to v3 and again from v3 to v4 but v4 cannot read v2's files.
