tjbaxter: I've tried that. When ever I run the LDK publisher .exe file, it crashes.
Hm, that's not good. First thing I would recommend is re-downloading the LDK just in case a file/some files was/were corrupted in the download.
Now, I don't know for sure, but I wouldn't think updating the game would have any effect on the LDK's functionality. If it does have problems with the new update, though, I would imagine re-downloading the LDK would fix such issues since I'm sure they would have updated it.
Aside from all that, try running the program as an Administrator. If you have Windows 8, run it in compatibility mode for Win 7.
Failing everything else, you would probably do better to contact the appropriate tech support. This forum and their forums are a bit dead, and at least some of the devs post on their forums. Good luck sorting out your issues.
