Lost all drive - isn't it ironic?

[Goran]

My car has no drive, wont go into gear.
Oh the irony
One of the major reasons I sold the automatic and bought a manual car was to avoid a gearbox failure.

I think I know roughly what it is, the clutch wont disengage. When engine is on gear lever wont go into any gear, when the engine is off it goes into all gears.
There appear to be no leaks between brake fluid reservoir, clutch master cylinder and slave cylinder. The slave cylinder is not loose. No drop in reservoir fluid level. Master cylinder is properly secured to pedal.
Looks like its the throw out bearing or the pressure plate.
This is going to be expensive.
