[mythtvnz] Corrupt database?

[Paulgir]

When I checked Mythtv (Mythbuntu)today I found it showing a language set  
up window that I had not seen before.I closed this window and was on the  
xfce desktop,I tried to start Myth frontend or mythbackend setup it  
reverts to the language set-up window.
I tried to do a database restore but I get this message:

Database Information:
          DBHostName: localhost
              DBPort: 3306
          DBUserName: mythtv
          DBPassword: XXX
              DBName: mythconverg
         DBSchemaVer:

          uncompress: gzip -d

Miscellaneous:

     change_hostname: no

Checking database.

Found 105 tables in the database.
WARNING: Database not empty.

ERROR: Unable to do a full restore. The database contains data





So what am I doing wrong - any suggestions?

The reason I tried to do a db restore was because I got some error  
messages when I tried myth_fill_database:







This version of MythTV requires an updated database. (schema is 1299  
versions behind)

Please run mythtv-setup or mythbackend to update your database.

Database Host: localhost

Or is this a good time to install Mythbuntu 12.04?
