Hello
I get the following error when i try to add a shp file to a map

I get this error only when i try to load the shp file from a network drive. If i copy the files to my PC I can add the map.
This what what I know
1) shp file is ok as it can be loaded from a local source and it will appear on the map
2) i used to be able to load it from the network drive a few months ago and it stopped. I just worked around it as i didn't have many shape files to load so it wasn't a problem. Now, i might be loading lots of shape files, so it will be a pain, plus data integrity issues etc
3) I can add the folder to the to the database and see all the shape files in the folders where the shp files are kept. It won't load from here when i drag the shp file to the map either.

4) I can add other data from the network folder to the map and not have an issue. The other data is an xls file while contains point data (lat/long).
Hope someone can help, thanks
Andrew
