Please start off with basic information:
- What OS are you using ?
- What version of electrum are you using ?
- Did you verify the signature of the file you have downloaded (to make sure you have the REAL electrum) ?
- Is electrum synced (green / red circle at the bottom right) ?
- Does your wallet contain the private key to the address you have posted ? (You can check that by opening the electrum console and typing ismine("1GK9Sp47tNuntYVHDPg5X3a8iZmLBK3fmU"). If it returns true, it does)
I'm using Linux Mint.
I didn't verify the signature of the file however I've received other transactions successfully.
The wallet does contain the private key of the address.
