I need some help.

Yesterday I sent all my nexus from cryptopia to the wallet I had just downloaded for Mac OS.

I am not sure I installed the wallet properly. I simply downloaded and install it. I didn't download the database or did anything else. I simply opened it and created a receiving address.

After many hours my coins still haven't arrived and Cryptopia says they are sent. I have no idea if my wallet is alive or not. I have no indication that any process is happening.

So I went back to the website and dowloaded the database, unziped it and copied its contents to the ~/Library/Application Support/Nexus folder.

Still I haven't received any coins in the wallet. Any idea how to fix this?
