Is this possible in some way or is the BTC lost because of the wallet not being created online when I have send BTC to it.
No, this is not possible.
Could you check whether the address you send the funds to: 1) is shown in armory as a
receiving address and that 2) it has received BTC (check on a block explorer).
If you can confirm both points, your coins are safe. Don't worry.
Can you please try the following:
- Shutdown armory
- Shutdown bitcoin core
- Reboot your computer
- Start bitcoin core and let it sync
- Start armory
If this doesn't help, could you then please upload the logs of armory to
pastebin or any other similair service and provide us the link here.
