You can deinstall and reinstall the system without loosing any data. Nevertheless you have to update database tables manually. Since I do not want to maintain update instructions for all versions I do only support the last few versions. This is why you have to upgrade from 0.7 to 1.4, then from 1.4 to 1.7 and from 1.7 to 1.9.
The esiest way is to deinstall uddeIM, delete ALL uddeim tables and reinstall uddeIM, so all tables will be fine. Of course all data will be lost in that case.
