Replay Issue

I have EB 1.2 installed over clean vanilla RTW 1.5.

I play an EB game against computer 1v1 using single player script.

I save the replay.

I can't find a load replay option in single player...so I tried multi-player script and i see that it does have a load replay option...it told me it might not work right...

In fact, it did NOT work right. It showed the boundaries for deployment, did not show the enemy units, and none of my units moved...it was almost like deployment stage. Nothing happened. They stood there for the duration of the replay. What am i missing here and what can i do to make this work, as I am interested in watching replays for both analysis and videocasting.

Thanks a bunch in advance!
