Ethereum - the wallet rebelled. How to reconnect to the network?

Question

Cryptocurrency

One fine day I start mist, but I can't switch to the test network from the main one. All buttons of rinkeby, ropsten networks are not clickable, hotkeys also do not work. In turn, the last 258 blocks are not downloaded to any main network. At the same time, the traffic is stable, as if everything is loading. Why is this happening?
Online wallets are not suitable - I need to upload my smart contract. Could this be related to the type of hard drive? I have everything on FAT32, somehow I don’t want to overtake data and reformat more than 300GB.

Answer 1

me everything on FAT32

Seriously?? In 2018?
Do you know that FAT32 cannot physically contain files larger than 4 GB?
Windows? Start - Run - cmd - convert /?
