You can not use the wallet.
All the people only concerned about the price, no one concerned about the application of technology
I disagree. If you read most of the posts in the last 3 months in this thread you will notice very little talk about price.
In fact I don't recall the cloak team discussing price at all.
As for the wallet: I've been able to use and sync the wallet on many different O.S. and network environments.
Help is always available. Just ask.
