Premature film rewind

Make sure the flash is coming up all the way. If it gets stuck even slightly down from fully raised, it will do what you describe.

I agree, digital P&S won't work as well as your Olympus. Plus all your shots will have to be stored on a hard drive-

It can definitely be fixed but let's try one thing before forking over few bucks to technician. Assuming it is a SLR camera, When you rewind, hold the rewind knob pushed in and try it. If you have a point and shoot, let me know which model. I'll be ready to assist when you respond either way.-James

The flashing E indicates the film is already rewound.   If you're concerned about it not being fully rewound, open the back in an absolutely dark room. A windowless bathroom or walkin closet will work. Block the bottom of the door with a towel or blanket and make sure there aren't ANY light sources in the room. No charger lights, smoke detectors, etc.
If the film is still hanging out, carefully handle it by the edges only & gently remove it from the camera. Try not to kink it. You can manually wind it back in the cassette by rotating the post on top.

Check the cleaness of electric contacts. If dirty, apply vinegar with cotton swabs and dry. Do not touch the mess cause it is caustic (gloves, maybe?).

No. You just rewound the film. The pictures you took are safe, but you probably 'lost' the rest of the film you did not shoot.
