HI
Im having exactly the same problem. Even asked in some threads some days ago.
Did you get the problem solved? Should I start to think about conspiracy theories?
I have been in touch with the Customer Service, they answer about every two days, they are polite, but it feels like they are not really wanting to adress the problem, as if they didnt understand it. As if they didnt know their product. They are aware that the send button in their online wallet is not working. And have told me that they are not in a hurry to fix it, but they expect it to make it functional this week.
Who understands...
Back to the prob: I also have that Hex Private Key, i suspect that it is encrypted in 256bits, at least according to the one tab that appears only when you open the wallet for the first time.
The strange thing is that I have been able to change my access pasword to the wallet everytime I open the online wallet in a new browser.
And the ressult when I reopen it in a new browser is always the same HEX Private Key. When I try to open it with other wallet providers, they find the Private Key to be in the wrong format, or not in a "private key matching format". Even tried importing it in armory.
When you open your wallet in Dgex it doesnt provide you with a downloadable .wallet file. Or any file. Just a browser tab where you have to decide the encryption and then it gives you a printable master key browser page.
Any help would be much appreciated.
New users DO NOT USE THE DGEX WALLET!!
