Dimmer Switch, 3-way switches and LED lights

Our kitchen has 5 switches for the overhead lights.  One of those switches has a dimmer, the other 4 are all just on/off switches.  Prior to making changes, everthing worked as expected.

 

We replaced all of the 9 overhead canister lights with LED "65 Watt", actual 13 Watt dimable bulbs.  After doing that, we started having flickering when the lights were on and periodic flashes when the switch was off.  The switches still opperated in the normal manner (on/off/dimming/different switches...).  I found out then, that not all dimmers work with LEDs.  I looked at a list of manufacturer tested LED dimmer switches and replaced the dimmer with one from the list.

 

Now, the flashes are gone (YAY), the filckering is gone (YAY), the dimmer switch works for on/off and dimming, but none of the other four switches seem to have any affect on the lighting at all (BOO).

 

Any suggestions?  In case it matters, the other four swiches are the kind that look like rocker switches, but when you press the rocker, they just click to change the state of the switch.

Several questions  need to be answered first: How many 3-way switches and 4-way switches did you  incorporate in this installation? The dimmer MUST be a three way with one more on the system plus 3 4Way switches IN THE MIDDLE. There should be 4 wire conductor (ie: 14-4 or 12-4) between the 4 ways and where they connect to the three way switches.Are all the 5 'switches' designated for the can lights?

  The dimmer should be the first device in the circuit with the next three  as 4 way switches and the last device a 3 way before actually feeding the can lights in series.

"The dimmer should be the first device in the circuit with the next three  as 4 way switches and the last device a 3 way before actually feeding the can lights in series."

Can you explain why it should matter WHERE there dimmer is placed in the circuit? An electrical circuit is just that, a circuit. Think "circle", with no beginning and no end. Furthermore this is AC or alternating current so there is also no forward or backward (and no first or last as you say.) The location you choose to call "First" is entirely arbitrary since the current flows both directions around the full circle.
