Italian Spell and Grammar check doesn't work

[fionnymy]

Dear community, i'm running office enterprise 2007 on a win 7 64bit pc. My issue is that the spell and grammar function does work for English and German, but not for italian. So long i've tried:
- uninstall and reinstall same version
- uninstall one version and install a different one
- rename the HKEY etc. file
- checked all settings in the word options



Has anybody an idea what's wrong?

Moreover in english and german the misspelled words are underlined, in italian not. If I hit the "spelling & grammar" botton on an italian text, a pop up messege says "there is not enough memory or disk to perform the check" (or sth similar). If I hit the botton on a different language, it alerts me that the feature is not installed, but after clicking "Ok" he does the check right away!

Plese help me
