No error. Just keeps on bouncing from the dock and all of a sudden it stops...
You could try starting it from the command line.
This should show you whats going wrong.
I guess I've lost my BTCs without being able to access the wallet. I had 30,0392 bought in mid 2011
No, you didn't.
Just because you can't get armory online, doesn't mean you can't access your BTC.
Start the old version of armory which works on your computer and export the private keys.
Armory does not need to be online to do so.
Then import these wallets into another wallet (e.g. electrum; but please verify its signature before installing). You'll gain access to your BTC again.
To export your private keys from armory: Click on Wallet properties -> Backup Wallet -> Export Key List -> Check "Address String", "Private Key" and "Include unused addresses".
Feel free to check the balance of these address in a block explorer before continuing to import them into another wallet like electrum.
If you decide to use electrum -> Create a new wallet -> "Import Bitcoin addresses or private keys". Then enter your private key(s) (without the address string).
P.s. Don't react to scam message trying to "help" you.
