thanks. I am also getting the connection error
You can fix this yourself. The Gadget points to an old, defunct link. First close down the gadget if it is running.
(1) Go to:
C:\Users\YOURLOGIN\AppData\Local\Microsoft\Windows Sidebar\Gadgets\MinerStats.gadget\js
(2) Edit main.js with a text editor.
(3) Find the line that begins with: var SlushPoolAPI ... and edit it to read: var SlushPoolAPI = '
https://mining.bitcoin.cz/accounts/profile/json/';(4) Restart gadget. Enter your Slush API token. Should now work! Tips appreciated, BTC address below!

Thanks! That edit works to fix connection problem. But code needs work, slush items like estimated reward don't work as is.
