I have got Google Maps working on my 8300 but I just get diagonal lines in BB Maps.

I was told by support to install maps across the top of the existing installation.

On examining the device the internet site gives the error message:

Error
Attempt to load an invalid file. Please try again.

I was then told to delete Maps from the device and take the battery out etc before reinstalling the application from the Internet. I still get the same message.

Does anyone have any ideas about what is preventing me installing the Maps application?

Thanks
