Lux in tenebris
Auto-translated
Dear UTER!
1) Uninstall and reinstall the *codecs*.
I recommend using (Vista-XP_Codec_Package).
2) Install TuneUp Utilities 2008 and scan the entire system with it.
Start with *One-Click*, then *Registry*.
3) If that doesn't help, let me know.
Евангелие от Иоанна, 1.5: Lux in tenebris lucet, et tenebrae eam non comprehenderunt. Свет во тьме светит, и тьма не объяла его.
