I did not back up old folder on the new laptop. So deleted the folder I copied into there and then when Jaxx started again (this time it loaded as normal) I had to create a new wallet, right?
You don't have to create a new wallet.
Now that Jaxx is working, just copy the
IndexedDB folder inside the
com.liberty.jaxx folder you got from the other PC to the
com.liberty.jaxx folder on the of your laptop (and replace it). This is where the wallet file is stored.
