OK. That address did get free CLAMs. You can see them here:

  http://khashier.com/address/xC4fvy3MWqsNtZEUguSDFkjNsnKoJS1X8H

(I found that link by typing "/dig 14m336CtF8PLrB8cLRoYpaSbeg2Zr2kDTM" into the Just-Dice chat area).

So either you didn't import the private key correctly, or you didn't rescan the blockchain after importing it.

Find out, by going to the debug console in the help menu, and typing:

  validateaddress xC4fvy3MWqsNtZEUguSDFkjNsnKoJS1X8H

When I do that, I see:

  {
    "isvalid" : true,
    "address" : "xC4fvy3MWqsNtZEUguSDFkjNsnKoJS1X8H",
    "ismine" : false
  }

Note the "ismine" part. That's telling me didn't import the private key. What do you see?

Can you tell me one of the addresses that should have CLAMs but apparently doesn't?
