Upgrading the Legacy Base Unit? Help!

I would try to recreate the base module again

Are you holding the button on the underside as you power it up?

Does the center yellow LED light up and then do you release the button?

Make sure you are following each step http://www.martye.com/TipsandT...duleform11042008.pdf

Tried again this morning and none of the flashing lights etc... that was supposed to happen  happened but it now says 1.51 on Cab and Base so cool!  I wish Lionel would package the thing with a USB instead of COM port.  My thought is , the easier to use and update, the more folks will not shy away from it.  Hardest part was finding a working com adapter   I eventually gave that up and dragged the system into work where my PC has a COM port and did it no problem!

Ed I had the same problem on one of my bases. The lights do flash but they're so dim and quick that you don't notice them. I tried several times thinking it wasn't done. I like you then looked at the version and it said 1.51. The lights on the other base visibly flash but the second was does not. Put a little reminder on the bottom of the base to check the version number after it seems to be done for the next time.
