1.4.5 version doesn't work, I've been trying all day with no succes. Where did you find 2.0.0?

Well, all coins are in the new wallet, so far so good. 

Daemon synced to 167000, but is always telling something like Sync data returned a new top block candidate: 167000 -> 17xxxx.

Now I'm syncing in my laptop, and daemon does show correct top block!

What's going on?

Having a hard time understanding, are you getting the correct or incorrect top block height? If it is the incorrect height, you will need to clear your data for the daemon. should be in

First turn off your daemon, then  navigate to the daemon files which should be located in 

C:\ProgramData\intensecoin 

in that folder, delete the folder labeled Imdb. This will allow you to resync. Turn the daemon back on and you are good to go.

Mining to your old address is fine, you just need to follow some rather complicated instructions to use that address in the new version wallet. I suspect this will be true even for the GUI wallet which will eventually be released. The instructions are posted to a reddit thread:

https://www.reddit.com/r/IntenseCoin/comments/89gw15/guide_converting_your_141142_wallet_to_the_145/

Very important: you have to extract the 4 keys from the old wallet (e.g. - 1.4.1 or 1.4.2) to restore that address in the new wallet. Do that now if you haven't done so already because those keys are also the only way to recover your balance if something happens to the wallet file (there is no 25 word recovery seed, AFAIK).

On both exchanges wallets do not work for a long time... it's finish...

can i just wait for the 2.0 gui and run that instead of doing all that stuff on the video? i can keep my coin on 1.4.2 for now, coin at rest are not at risk right?

You are now synchronized with the network. You may now start intense-wallet-cli.


transferred all funds to a new wallet. All OK

Spoke too soon. It was syncing to that, but now it's showing 174843 again. I really can't figure it out.
