[I need help.] Balance problem

[MetaL]

Can anyone explain why there is a balance in the actual wallet address, but the desktop wallet is zero?
Here is my wallet on the block explorer is https://explorer.stacks.co/address/SP1DSWY24GN4M2GBAK7TND0J8BB9ET42M5K1TCKPT?chain=mainnet .
I tried to recover the wallet with my Secret Recovery Key, but it’s not working. So I need an answer to the problem.

Thanks.

You’re using the Stacks v3.0 wallet which cannot communicate with the Stacks 2.0 blockchain.
You need to upgrade you wallet to the latest software: Hiro Wallet for Desktop
and then restore your wallet with your recovery key (your backed up 24 word “seed phrase”).
