Problems with MajiPlayer in ROKR U9

Problems

Majiplayer sends me the following message when trying to find the songs:

Menu > Search and then the ERROR

Error
An internal application error ocurred:
java.lang.SecurityException: Application not authorized to access the restricted API.

Any way to fix this?

Motorola doesn't allow untrusted applications to access the filesystem which causes this error. That is why Motorola devices must use the trusted version of majimob and install it over the air http://majimob.com/mob/ you must choose the version that doesn't say unsigned for Motorola.
The problem with this is that many operators especially in the USA remove 3rd party certificates from trusted sources such as Verisign (which is what we have) hence that version won't work.
If this is the case there isn't much we can do, we would advise you to contact your operator and complain about the closed nature of their application platform or buy an "unlocked" phone.
