Try to run their wallet on an smartphone app if you have one. I had some issues before with them and was because my browser wasn't updated tho for me some scripts would crash...
Anyway have you made a backup of your private keys? They let you do that with those random words from which you have access to your coins - if you have this backup you should be able to use your coins without a hustle, you don't even need blockchain.info to send your coins then.
Same with smartphone app , unable to login ,if I click recover funds and enter my pass phrase I get errors.
