Reverse gear getting locked up

Did you adjust the clutch pedal for a lower friction point?
Was the transmission out for any reason?
Any sponginess to the pedal (Air in the lines)

Typically Reverse is the first to lock out when your clutch is dragging and not fully disengaged. Reverse is followed closely by first gear being stiff or locking out completely too.

Does it simply resist going in or does it feel like the shift gate isn't there?
My second thought would be the reverse lockout plate on the shifter may be off a little and isn't allowing you to fully reach the reverse gate.
