In short:
In following posting you will not fine a complete package due to the forum restriction of 200kb:

I have removed all files which I have not changed, so you have to use the files from the latest release (0.5b).
There are two ways to update:
1. Compile a new package: Use the original one (0.5b), overwrite the files with the new files and rezip the file. Uninstall the old one and install the new one, update the tables.
2. Update the tables and overwrite the existing files with the files provided in the zip file.
When you compile a new package and do a fresh install the new installer automatically creates the missing table fields.
