We have contacted them to advise them of the latest update to 10.7.4.
Maybe it's something to do with them ceasing trading.

We are looking for a solution
Any node that can connect to the mine pool should try to restart the wallet to synchronize the blocks
38.27.97.24

Both pools are back online.
Please try to connect the following nodes and restart the wallet to repair
58.221.87.50
38.27.97.24
47.92.129.82
47.52.19.237
213.32.98.226
203.78.141.213
185.191.228.162

Freiexchange contacted me earlier and i have passed on the details to the dev.

We have adviced our exchanges to reduce confirmations to between 50-100 for now.
The previous high number was just a precaution for a temporary period.

We are continually trying to notify these listing sites, they are proving difficult to get in contact with and update their records.
If you download the latest version you will be able to synch the wallet.  You can always add the latest nodes list from cryptoid blockchain explorer which is up to date. Here:

The link was posted earlier today, just a few posts before yours.

I understand your concern.  I asked for clarification yesterday and have been told "as soon as possible".
I will update when I get some more details

The addition of Masternodes also means that Quark will now have a development fund to use for future projects.

If you're talking about Quarkchain then you're in the wrong thread.  Try here.  https://bitcointalk.org/index.php?topic=3587645.400

Wait for the next version which will be released in the coming days.
The support is appreciated.

Our developers are currently working on the code and version 10.7.2 will be released shortly

Try freiexchange  qbtc, aex, novaexchange, finexbox.
Look on page 1 of this thread and check stats here.

There's an explanation on page 25 of this thread.
The most important thing to do is backup your wallet.dat file.
Once you have installed the new wallet version you'll need to copy your old wallet.dat file over.
Let us know how things go.
Good luck.
