I cannot import a database from SuperMemo 7. Why is the import process interrupted?
There is a bug in SM7IMPRT.EXE that makes it impossible to import from some earlier versions of SuperMemo 7. You will need SuperMemo 7.5. Open the database with this new version, run Tools : Garbage with Compact checked. Then import the database to SuperMemo 8 again. The corrected version of SM7IMPRT.EXE is available from this site along the new version of SuperMemo 8.
