What information would you like me to post that might help in the diagnosis of the problem? I performed the following steps

1) Opened DVD using UltraIso
2) Copied the entire DVD to the POIson folder
3) Launched POIson pointing to the POIson folder
4) Added about 5,500 camera POI's
5) Created a POIson1 folder within the POIson folder
6) POIson copies all orginal files to the POIson1 folder
7) Save the changes. This is when the error message appears. There is an error message generated for every POI imported. The program continues through and saves changes. See the first post in this thread for the error message
8) Create an ISO using IMGBURN from the files in the POIson1 folder
9) Burn the ISO using IMGBURN
10) Maps are visible on the NAV but no camera POI's are visible.

Thanks in advance.
