Asset creating process loads forever with no result

[tector]

I wanted to create my own asset with the wallet (v0.7.0 on Windows 10).

I got iota tokens from the faucet (guess i need some for the asset creation?).
I was able to enter Name, Symbol (4chars) and Amount (amount is less than i have tokens).. then i clicked OK and the process seems to start.
However: The loading animation runs forever without any result.
Then i've restarted the wallet but nothing was created.

today i tried it again.. now i can see an errror:
