Ok, lets try a think
Start stellite-wallet-cli and connect to your wallet.
Type this : spendkey (save them) and viewkey (save them too)
Your screen could be like this :
[wallet Se3wnd (no daemon)]: spendkey
Wallet password: ******************
secret: e855c0f14ff7f56a9d08c643e2eba46000fb0ddce2cbf00434d049c62d43a20b
public: cef59451335ff73e76ac26856564b9d929128d6923026cabc0168de39eb6ed81f
[wallet Se3wnd (no daemon)]: viewkey
Wallet password: ******************
secret: d17e158cf59f06c5b6f6663451783136b826f010baf1670dae2bb7b9574cc70c
public: 2bdc7fa1b2176c288db201e6bf12f53c6e768250ab7444af5fcddf61856093a6
Now try to restore your wallet using your secret spendkey with
stellite-wallet-cli.exe --restore-deterministic-wallet
Tell me your results... Thanks
PS : Have you tried before to delete all files in C:\ProgramData\stellite and launch the sync again ?
