N8DBB: This is what I would try. If they are showing up in the DM (where it lists all of the applications on your BB when adding or removing software), I would check/uncheck (whichever it is) to have them uninstalled and then after it is done doing that, I would go back and load them again through DM. Ultimately you may just be running into a problem that is specific to the software your carrier has installed from RIM and the version of 4.1 you are running. I still have the Hong Kong CSL, but you might want to try the Cable and Wireless version instead. Ultimately you are dealing with a VAST number of variables and playing around with it may be the only way to solve it. If all else fails, I would backup, wipe, and reinstall everything from scratch.
Shiirley: I am at a loss almost as to what to tell you. I havent checked to verify and believe what you posted about how plazmic's site says it is compatable with 4.0, but personally I think that is a typo or something (on their site not in your post). In other words, as far as I know - ALL themes that require Plazmic reader also require 4.1. In other words, before I installed 4.1 - I installed the reader and a theme I had found out there called Steel. I could see it in my applications, both in fact. It didnt show up under themes however and I could never activate it untill I loaded 4.1 and low and behold - there it was. My advice to you is just that. Try out the CW version of 4.1 and then go from there!!!
Good luck to both - HAPPY THEMEING!!!
