_UE_ Descriptions instead of correct descriptions

I have attached a file that shows some screen shots that show the problem I am having since installing CB Subs. I am seeing _UE_ etc instead of the correct descriptions. Hopefully this is easy to fix. Site works fine except for this.

looks like your CB install did not finish properly - please try reinstalling CB 1.3.1 over your existing J1.5.22 environment.

CB was installed with newest version (working fine for weeks) and then I installed CB Subs and this is what I got. Do you still suggest a reinstall of CB? Will I also have to reinstall CB Subs?

The issue appears to be related with default language files missing, so CB install should fix it.

I cannot see how CBSubs could cause this - there should be no need to reinstall CBSubs.

Reinstalled and now CBSubs is not working and says that files are missing. I could reinstall CBSubs but I want to make sure I am not going around in circles.

How exactly dd you reinstall CB?
It looks like you uninstalled it and then reinstalled it.

Since you are on a Joomla 1.5 environment this was not needed.

Now you have to reinstall the CBSubs plugins (and any other CB plugins you had previously installed).

This should bring things back to normal.
