I have a problem that does not seem to be answered by any previous forum entry or ESRI support pages. I simply tried to use the Project Raster tool to reproject a raster layer. It has worked before (with a different layer), but now I get this error:
In the description it says: "The spatial reference of the dataset cannot be altered. The dataset may be in use by another application and therefore locked." But I don't really know what to make of this.
Please, can anybody help? Thanks very much!
