Mining freezing after auto update
I've had this happen on all my machines for a couple updates now. It seems like it updates then just freezes and doesn't do any mining.

In the powershell window, the last logs I see are:
```
Version checker: New version 4.0.1.3 found.

```

The GUI run window says:
```

Everything just stops there until I manually close nemosminer and reopen it, then it launches the new version.
