I’m sorry to hear about your loss of Lisk.
Lisk gave only a few days notice about the hard fork and SatoshiLabs issued a warning to Lisk users as soon as the message from Lisk were announced. In that warning it was said, among other things:
The short notice given regarding this issue is due to the fact that Lisk did not provide any notice of the incompatibility ahead of time nor did they reach out to discuss a solution or workaround.
About warning Lisk users through email, SatoshiLabs don’t save user data for more than a short time after the items in the store have been shipped, so they don’t have user emails to send to.
You should take this issue up with the Lisk people, where it belongs. I don’t know, but perhaps there’s a way you can get your funds back. If there is, they’re the only ones who may help you until a technical solution is presented to SatoshiLabs by Lisk developers.
