Fresh update courtesy of ChekaZ:

I have not heard of any PoS pools for TZC but I will ask around.
I would guess it would not be likely though since "pooling" your coins is much more risk than pooling your PoW mining hashrate--you would presumably need to give ownership control of your coins over to someone else and there would be no guarantee of getting them back? 

Yes, that's right. I assume, that this is the reason why using pools for PoS is not that popular.

Could you explain more in detail what you mean?

I believe there is some information about solo-mining in the general or mining guides you can find on the TZC website.
It's also possible to find some info around the web if you look for solo-mining with qt-wallets or with the getwork protocol, etc.
Also, if you check the readme info for various miner software, there is sometimes info in those as well.

Thanks, added Information to get Trezarcoin listed for voting.

Apparently there was a glitch.
I think I saw a message indicating that WTM has been contacted and it is expected to be resolved soon?

Please try the standard suggestions:

1) Using the command line, run the wallet with the -rescan parameter.
2) If that does not help, please run the wallet with the -reindex parameter. (This may take 10-20 minutes or more depending on your CPU/storage speed.)
3) If neither of the above work, (after ensuring that you have a recent/fresh careful backup of wallet.dat) please move or rename the /data folder. Then launch the wallet--it will need to resync as though this were a fresh install. Once it is done, please close the wallet application. Then replace the new wallet.dat with your backup. Then try reopening the wallet and verifying that your addresses are present, etc.

If none of the above help, please visit the Slack/Discord #support channel where someone will be able to offer further suggestions.
Good luck!
