Manage themes error

Everytime I try to access the "Current Theme" or the "Themes and Layout" on the Configuration, I get this error:
Fatal error: Call to undefined function ThemesMain() in /home/sites/redstar.ro/public_html/eve/forum/Sources/Admin.php on line 494
Any ideea?

Have you done any recent modifications or file edits to your SMF install?

[redstar2k]

No modification, just installed a fresh one.

Could you check your Sources folder for Themes.php? Thats all I can think of right now :/
