I checked the MD5 checksum code, and it has changed as suspected: 488a4606c30cd32495963de0dcc64da9 I disabled a bunch of security and antiviral programs, and tried again. No change. I can find a 1.0.2 compatible KSPAIExtensions.dll plugin file from another source, but its the second plugin, launchpads.dll, that is the crux of my problems. If I had access to that dll file in a 1.0.2 compatible form, I could get EPL to work manually. Unless there are other plugins besides KSPAIExtensions and Launchpads in the 1.0.x version. Not that I'd know about them....
