Reflection problem

I'm working in AE 7 (WinXP Pro) on a comp that uses the Reflector plug-in several times. I moved the layers in the timeline and now the plug-in stopped working for a portion of the composition. I've refreshed the Reflector several times, to no avail. Another portion of the composition has Reflector being used without any problems.

Any ideas? My client is waiting and I can't get my reflections to work! I've have the layer receiving the reflection directly beneath the layers being reflected.

Thanks.
