Seems the format of the swype database has changed in pr 1.2.

When installing the old database file for (for example Polish) it gives an error. The same goes for when some language is replaced by the .zdb.le file of another one that worked in 1.1.

edit:
Checked the swype data files from 1.1 and 1.2 and they are different. Size, and the file header.
