The e-mail I used fod my Dropbox account was hacked and I no longer have access to it. I have tried to change the address in settings, but the system will not accept the new address. Every time I log on, Dropbox informs me that it can't access my e-mail address and I may lose my Dropbox account. I won't receive an e-mail telling me that there is an answer to this, for the above reason, so I hope I find it when there is one.
