Since the last wallet update (12h ago) I can't get anything staked, all orphaned

The new staking parameters resulted in many, many transactions' suddenly becoming full weight.
Orphaned stake reverts back to your wallet and continues to age. You generally do not lose interest on orphaned stake, although it does clutter your wallet with orphaned transactions.
After about 4 or 5 days, these orphans should become much less frequent as the EBT in circulation begins to obtain a more even distribution of weights.
You can minimize orphaned stake by consolidating your transactions, giving them more coin-age and thus a greater chance to find a block before becoming orphaned.
Please be patient. Your reward will be 100% APR on your EBT.
