Try some PB Blaster on the bleed screw. Let it soak for a day then re-spray. Use a 6 point socket to avoid rounding over the hex shape.
DOT 3 is OK - DOT 4 is better.
Also, the slave cylinder can rotate in its mount. Make sure the bleed screw is uppermost - at 12 o'clock.
How is the flex hose? If there is any doubt about its condition this'd be the time to replace that, too.
