hi zanix,
I'm working on the translation and I've nearly completed the whole file... but what do you mean with:
$lang['sql_error_addons_files_insert'] = 'Could not insert addon files\' data';
do you mean "Addon file-data" or "addon files or data" or " 'addon files' data"?
Oh and by the way: your Introdescription has an Error:
When you upload an addon to this system, and hit [Update] in UU, UU will look up the "Synchronization URL" (the one in the frame on the left)
this button is called synchronize
oh and the file hasn't got any "?>" in the end.
