you have several possibilities:
1) You can install the version 126.96.36.199 again and I´ll send you the License Key - as was written in the beta invitation mail, we offer the new version to our previous versions customers for free - just for a feedback how they like the new version. So if you like the new version, you could install Sticky Password 4 for free and restore your current database.
2) You can restore the database in Sticky Password 3.4 - but Sticky Password won´t be able to restore the accounts which were created when you were using Sticky Password 4.
If you agree, I think that the best way will be to reinstall Sticky Password 188.8.131.52 and obtain the License Key.
Sorry for inconvenience.
