is it possible to access paid apps on different phone?

Id like to try some apps I purchased from my original droid and try them on a droid x. When I try to log into the storage locker, it says (invalid or bad credintal)...
Do I need to deativate my storage access from my 1st phone or what?

Nope

Make sure you login to StorageLocker with your username/password and not your email/password. Avoid also sending any extra characters such as the 'enter' key within the login fields.

same issues

I am having the same issue as above person! I put my username not email, and its still saying same thing! I contacted helpdesk and havent been contacted back. So now what?
