From the original file:
PatternCommunicationCall=30;1;0;0000;0000;40007f00 017f017f050001ff01ff0000

From corwin's third example:
PatternCommunicationCall=30;1;0;40002000200040ff20 0020000000;0000;0000

If you copied the third example directly into your mce.ini then you've changed the flashing pattern. You should have just moved the original pattern from your mce.ini file to the correct channel.

@corwin:
I dunno - I must accidentally click it a lot *points to "Thanks!" count*
