Realone player build 6.0.11.872 with a CREATIVE SB LIVE DRIVER & PENTIUM IV 512MB RAM AND 120 GB HARD DISK.

WHEN OPEN THE REAL PLAYER AND. FILE-OPEN-BROWSE
THESE WORKS OK. BUT WHEN I USE THE WINDOWS EXPLORER AND OPEN DIRECTLY FROM THE FILE THIS HAVE THE ICON FROM REAL PLAYER BUT DON?T WORK AND THE TASK LIST SAYS ( REAL PLAYER DON?T WORK)
I DONE:
CHECK FOR ANY VIRUS
CLEAN THE RECICLE BIN
CLEAN THE TEMP, COOKIES Y ROBS WITH AD-AWARE AND SPYBOOT
REINSTALL THE REAL ONE PLAYER
UNINSTALL THE WINAMP PRODUCT.
