http://i39.tinypic.com/2uxvbs1.jpgThen i open the web browser in the address
http://localhost:8989/ And i get the next info in the console:
http://i40.tinypic.com/27zkhnn.jpgAnd when i set the path to my wallet and try to dump it, i get the next error in the console
http://i44.tinypic.com/2mhy6vk.jpgShould i follow the first warning and install that package?
"WARNING:root:pycrypto or libssl not found, decryption may be slow
'ecdsa' package is not installed, pywallet won't be able to sign/verify messages"Thank you
