Well, few days ago everything was fine, the wallet gui works perfect and i had 10k btcz, then i opened the wallet and the famous error apear, A general unexpected critical error has occured: error : couldn´t connect to server: EOF reached (code 1) (make sure server is running and you are connecting to the correct RPC port). The solution in other thread was to erase all the archives except for the wallet.dat, didn´t work, same error. I also tried to open de wallet.dat archive in another pc, same error, well i think i am going out of this project, i lost time and energy spend mining this altcoin. If someone have another solution please let me know.
