This 4.45 release is (unfortunately) not backwards compatible with 4.43 and 4.44 for date-strings. See the following release notes on how to update your data and how to set the database format to continue to use the 4.43/4.44 format.
Sorry for the problems. Here's the full change list:
* CORE: Fixed bad bug introduced in 4.43 that broke date-string backwards compatibility. Thanks to Howard Liberty.
* ANDROID: Added better exception handling around inner classes. Thanks to Jonathan Caryl.
* ANDROID: Fixed bad problem with recursion and OrmLiteConfigUtil. Thanks to Jonathan Caryl.
