Problems translating multiple lines

I am translating osqa to catalan. I translate all the strings but I have peroblems with al strings that have more than one line. OSQA shows the text in English, ignoring the translation.

Here is an example, I just translate the first two words to test, but I can't see it on the web.

  #: forum/skins/default/templates/auth/temp_login_request.html:8
msgid ""
"\\n"
"    If you're experiencing problems accessing your account, or if you forgot "
"your password,\\n"
"    here you can request a temporary login key. Fill out your account email "
"and we'll send you a temporary access link that\\n"
"    will enable you to access your account. This token is valid only once "
"and for a limited period of time.\\n"
" "
msgstr ""
"\\n"
"    Si tu estas experimentat problems accessing your account, or if you forgot "
"your password,\\n"
"    here you can request a temporary login key. Fill out your account email "
"and we'll send you a temporary access link that\\n"
"    will enable you to access your account. This token is valid only once "
"and for a limited period of time.\\n"

Any idea?
