Hello,

I am on the Quark (QRK) foundation and we are in the process of releasing the latest version of our wallet. It can be found here.
https://github.com/quark-project-evolution/quark/releases/tag/v0.10.7.5

Even though Quark is the 3rd most copied cryptocoin, Quark (the original) is PoW/PoS/Masternodes, quite unique in the crypto space. 

Once mining, a link will appear on the front page of our bitcointalk page, all social media and our website.

We hope that Quark can be mined at your site soon and we look forward to working together.

Please don't hesitate to contact me for further information.

Best regards,

For now the new release is Linux and win64.  The new mac version is a little further down the road.

0.10.7.5.  Official launch mid October.

https://github.com/quark-project-evolution/quark/releases/tag/v0.10.7.5

There is a development team working on it at the moment and testing will follow immediately.
Just try and be patient for a little while longer.
There's not much else I can say right now.
I am in communication with frei and we really appreciate their continued support.

This is due to the 000bug, that's what needs fixing.
The wallet just needs a restart.

Here's the block explorer again.

Freiexchange informed me on Feb 17 that the wallet was in resync.
Have you tried to contact them?

Here's an old guide to windows' wallet setup.  https://www.quarkcoins.com/mining-quarkcoin.html
With the introduction of special mining machines for Quarks, it's hard to rely on your own computer to do the digging.
Here is a mining pool you might want to join?

Freiexchange have just informed me that it's currently in resync and will pick up transactions once it's up to date.

With the message "no blockchain available", you might need to add some working nodes.
You can find them here (click on Node List): https://chainz.cryptoid.info/qrk/#!network 
Here is the up to date blockchain: http://www.nodepow.com/site/block?id=305
Regarding your wallet, you first need to make a backup of your mac wallet.dat file.
Then replace the windows .dat file with it.  There are plenty of guides about how to do this and where to find the wallet.dat files on the mac and pc.
When the issues with the superblock are fixed, a new pc wallet will be released, followed by a new mac wallet.
Have you tried all the exchanges on the first page.  As far as i'm aware Freiexchange are still accepting deposits, and perhaps the others too.  I know that AEX is temporarily closed for deposits.
As i have stated, the issues with the code are being worked on.

AEX will reopen deposits when the issues with the superblock have been fixed.  It's being worked on atm.
Any updates will be posted here.

The list of exchanges was recently updated on the OP.
