Fonts disappear

[SupaFlyer]

I have problem with inventor about missing fonts, i try to edit my previos text and they disappears when i click ok. This annoying thing started when i edit customer DWG files and i save it as DXF, nothing unusual. I though it is about something with layers and imported settings, but i dont find anything what is changed. Sry my lousy english..

If you have recently installed any Microsoft Updates, they could be the problem.

Uninstall Microsoft Hotfix KB918118. This is a verified problem.
