when i tried to clean unused folder, i thought "texas" folder is a game
so it got deleted

and know message "your mass storage controller driver is not installed"
"please insert the cd-driver"

i don't have the cd, so i tried to use recovery program but nothing scanned

mine is acer travelmate 4720 with vista 64-bit
i try to search for texas IEEE controller and texas PCI controller but none for vista 64-bit

the PROBLEM is ANY MEDIA PLAYER I HAVE ONLY GIVE SOUND
THE VIDEO DOESN'T SHOW ANY PICTURE
and somehow, ALL MEDIA PLAYER SCREWED UP
i can play mp3 or any audio files but NOT MUSIC VIDEO one.

so what mass-storage-controller program should i used??????
(i don' mind anythin' as long as that message dissappear n my video can show its picture)
