Identity Safe on Android won't let me log into Vault

Hi there

 

I have the Identity Safe app on my Samsung Galaxy S2. I used to have no problems with it, but now it won't let me log in to my vault.

 

I have tried several times, and I have double checked that I am using the right password, but I keep getting an error message saying it's the wrong password.

 

Has anyone come across this before? Got a solution?

 

Thanks

Brett
