Login module error. _EU_??

I've migrated to J3.3 and upgraded to CB 2.0.5. My previous login module from RizVN doesn't have an update so I set up the CB module.
What is _EU_ in front of every line and how can I fix it?

I attempted a reinstall of CB but it won't let me (duplicate)

The EU prefixes are the language strings. It seems that the language files are not installed or something else in the install is incomplete.
Normally you can install CB over CB without problems. How exactly are you doing the installation?

I was trying to do a reinstall with the file pkg_communitybuilder_2.0.5+f26954917 in 'Extension Manager'.
Is there another file I could use that contains the language files that may noy be considered a duplicate and be rejected by Joomla?

I found another instance of the CB Login module and published it. The '_EU_' is gone and the module looks clean. However, I now get the message "Error: CB Login module not created (required)." when trying to log in.
Yes, I followed instructions.

Any suggestion on how to do a reinstall of CB 2.0.5 (package)when Joomla3.3 stops it saying this is a duplicate?
As suggested, my language files are probably corupted or missing something.

Okay, I downloaded a fresh CB2.05 and tried to install it via Extension Manager.
I get this error;

1062 - An error has occurred.

Duplicate entry '17' for key 'PRIMARY' SQL=UPDATE `gic_comprofiler_plugin` SET `id` = 17, `iscore` = 1 WHERE (`element` = 'cbarticles')

Return to Control Panel

Since my issue may be in the language files and a reinstall was recommended, what is this error and is there a work around?
