Thanks to Brian and Rick for pointing out the availability of a hotfix for Raster Design 2010’s standalone/network license incompatibility. As a bonus, it also fixes some Raster Design / Civil 3D stability issues.
Note that although this fixes the most common scenario where a network Raster Design needs to work on a standalone AutoCAD, it does not fix the opposite scenario. So if you have a bunch of network licensed AutoCAD variants available to you and you have a standalone license of Raster Design because you’re the only person in the office who needs it, you’re still out of luck. If you’re in such a position, I think you have a very strong case for a no-cost change from standalone to network licensing for Raster Design. If you ask for this and are refused, let me know and I’ll let everyone else know.
