Return of Reckoning

Ever since I installed RoR on a brand new computer, I keep getting crashes every time I leave any of the "safe zones" (cities or chapter camps) with any of my chars. Game doesn't give any error, it simply terminates to desktop.

Other strange behavior observed:
- instead of music, nasty screeching sound is emitted, until I turn off the music in game settings (doesn't fix the crashes though)
- sound effects play for a time, but often get stuck in a loop
- NPCs don't speak when you talk to them
- mobs and players sometimes appear to move/walk backwards
- animations of chars in the character selction screen are noticeably slower

I tried reinstalling and repairing the game couple times, without effect. I don't have any mods installed.

Any ideas what could be causing these problems, where should I look?

Most likely not complete install.

- First point is probably audio.myp is corrupted or not fully downloaded.

- Second one is vo_english.myp is corrupted or not fully downloaded

- NPCs don't talk is related to the issue above.
- Walking backwards happens when game runs over 100 FPS.. switch to 32bit from Launcher to have 100 fps cap.
- Animations slower, that's usually when the window is out of focus, it reduces the FPS.

Looks like re-downloading the files fixed it, thank you very much for support
