I made a transaction yesterday and it is not appearing in my electrum wallet.

The id is:
5b3cf0f09572154349136ad6db10f84d97373ad31620c5081c882e9fc34aca2d

The receiving address is:
1GK9Sp47tNuntYVHDPg5X3a8iZmLBK3fmU

It was for a small amount, just to see if it would get through, which it hasn't. It has been deducted from the sending wallet.

I've tried restarting the electrum wallet and it makes no difference.

Any ideas?

Thanks.
