Getting tired of getting error code -4. Just as well I kept my IPO investment low.
That error happens when you already imported your private key and trying to do it again.
After you import your private key your tx won't show up until you exit the wallet and re-launch it again with -rescan.
heavycoin-qt -rescan
That give me the following message
Method not found (code -32601)
Maybe I need sleep
guys... close wallet and go into window cmd console.
