Try xtri on Discord.  They may still allow you to direct mail them your info.

You will need to send the following to them from your old wallet:

1. Secret View Key - You can export it or copy it from your old wallet.

2. Your old wallet address.

3. Your new Helium wallet address.

After you copy the keys from your old wallet (I would copy all 4 keys and seed) save it to a flash drive.  Then go to C:\Windows\Program Data and delete the triton folder.

Then download Helium and install it.  Then you can get your new xtri address.
