Vechain SYNC wallet issue

[Bigfoot187]

Trying to move my VET tokens from the SYNC wallet, but after following prompts for my Ledger-NanoX seems that my transfer fails when I get to step 4 (checking account info). What's happened ?
-- I can see QTY of VET in the Ledger Wallet displayed in SYNC but cant transfer them anywhere due to transfer failing -- when I get to step 4 (checking account info). There is enough VTHOR in my account and there has never been another ledger coupled to the PC SYNC is on. Anyone has any idea how to fix this issue? It seems like the ledger wants to import new VECHAIN adresses and doesnt remember the old but when interacting with the "old" adres it gets stuck on step 4.
