Maybe this reply is a little bit late, but there´s an easy way to recover your bitcoins from HIVE-Wallet:

1. You need your 12-phrase-password!!! Very important!!!
2. Go to https://coin.space/
3. Insert your 12-phrase-password
4. Insert your four-digit Hive PIN

That´s all! Sometimes the site is loading a little bit longer, but you get access to your bitcoins from hive wallet an you are able to transfer them to another wallet!
