Just use an exchange wallet. If you're not able to get a regular zclassic wallet working then you probably should just use an exchange wallet. What do you plan on using it for anyway? You can mine directly to an exchange with zclassic. If you're looking to do some long term holding then exchanges should be fine too. I believe gone are the days where exchanges run away with your money. Just pick one of the big exchanges like bittrex.
I'm a Bit Hesitant on long term Holding to exchange, Running your money away is not an issue but the security concerns, they are always the target on hacking.
Local wallet is more secure if you could set it up properly, but a little pain when it upgrades that you need to act upon otherwise will not work.
