hmmm, sounds like you just installed quicktime.. am i right? or maybe messed around with quicktime settings? depending on what resources you have available (norton's ghost, Go Back) and what operating system your using (XP, 2000, ME), you may be able to restore your sysytem resources to a pont before you came accross this problem. Quicktime is notorious for changing system setting to make your OS use quicktime for everything. perhaps you may want to look into un-installing quicktime and all its components. perhaps your system will default back to where your files are at least usable.
