Projecting error:invalid extent for output coordinate system

I have some GPS data which has been collected using WGS84. I�??ve downloaded the data and saved these as csv files (I can�??t return to the device and import directly using DNR Garmin etc, as its been re-used). I�??m trying to get the projection from this data to match up with British National Grid.
I�??ve added the data to the map (using Tools -> Add XY Data and set the geographic coordinate system to WGS84). When I compare it to the background raster data (projected in BNG) it looks slightly offset, so I know I need to re-project the WGS84 data to BNG. When I use the project tools to project WGS84 data to BNG, I get the following message:

ERROR 999999: Error executing function.
invalid extent for output coordinate system
Failed to execute (Project).

Can anyone help?
I�??ve attached the metadata (from ArcCatalog) for the GPS data. Its driving me potty and I reckon it must be quite simple... Thanks for reading!
