New version to OS 5

I had this app on my iPhone version 4.3 and it worked wonderful. When I updated my iPhone to OS 5, I had to download a new version of Navionics to run on OS 5. This new version is not accurate and good details of the lakes and bottom contours dont exist for most of the lakes. When will it get fixed?

FIXED
Ive downloaded the Lakes of US & Canada to my new iPhone 5 and the accuracy is fixed and it works great.
