I can't get the wallet to sync.

Been trying for a few days now, both on Win 7 and Win 8.1.

It crashes on around 6 days left to sync and I get this in the debug.log:

EXCEPTION: St13runtime_error       
CDB() : can't open database file wallet.dat, error -30974       
C:\Dev\Wallet\riecoin\riecoin-qt.exe in Runaway exception       

2014-04-13 20:22:21 EnvShutdown exception: DB_RUNRECOVERY: Fatal error, run database recovery (-30974)

Wallet is v0.8.7-beta, I have deleted all in roaming several times (not wallet.dat) and it starts up fast in the beginning but after a while it is really slow to sync, takes longer than a full Bitcoin sync I would guess if it ever would finish.

Any hints or insights on what I could try? Not using a .conf file either.
