Sandbox login issue?
I have created two sandboxes at a time in free 30 days trail edition. But even though I successfully created I cannot login to sandboxes by username suffixed with '.Sandbox name' and used production password.
Try resetting the passoword
If you have a salesforce support then you can raise a case with them to troubleshoot further..
