No Tick Replay

[swan]

Hi,
Running Version 7.4 (build 608) trying to use Tick Replay for first time. (for ES Z3 data)
I have followed all instructions for downlaoding and creating tick replay data and file.
I get the box up to chose play within a "$playback" chart, however chart stays blank and no progress in the "status" of the replay.

Any help appreciated.

thx
Edit..By using symbol $INDU tick replay works..does it not work for ES Z3 or any futures contracts..?
thx

Edit 2
Got it working.. have to use "jump forward" button until ticks appear..
