How to resolve this problem

Is Komodo coins able to buy now? If yes, where can buy it?

Yep it should available and openly traded. You can buy any from Bittrex, Cryptopia, CoinExchange and Cryptox. Bittrex has the highest volume but it depends which trading site you are most comfortable.

is the JUMBLR airdrop paid? Not showing in my wallet, cant find much about it

Yes the Jumblr is paid. I am working on a Jumblr command line guides so people can see and use their Jumblr through the cli.

It's probably better the coins stay with KOMODO for later

To claim your interest. You can just send .001 kmd to yourself and wait for the 1 confirm. You will receive your interest that is it

I'd really love to know this too. I can't get the wallet synchronized past about 93% before it crashes with that same error message. So I can see my wallet address, but as I can't synchronize beyond February this year, I can't access my coins etc.

I have just accessed my private key, though - can I use this to create a different wallet in the Agama wallet? Is this a better way to go?

EDIT:
Also: is it normal to only have 8 connections? Synchronization is extremely slow, even though komodod.exe is using around 4MB/s bandwidth.

You are very helpful, thanks. But why don't you write on the website: you shouldn't use Agama or Swing now or something?
Many people are wasting their time because of these problems and therefore you waste your time too .. this is it!

It's important to keep the wallets up since they work for some people. Yes we get bug reports but that's how we pinpoint them and fix it. So for now the wallets remain on the website and we are taking care of providing as much support is necessary to allow users to access their funds.
