Stan,
I installed the build 971 and now I am trying to install winsum-1.0.4.
Following the usual procedure, winsum-1.0.4 plugin is present in the Plugins folder in the EL, but unfortunately, it is not listed in Lottery --> Preferences --> Plugins, and is not accessible to the user.
Actually, both old version of winsum (version 1.0.2) and winsum-1.0.4 can be present in the plugins folder at the same time. The new version does not overwrite the old one. However, in this case only the old version is accesible to the user (recogniseable by its familiar appearance and lack of new features).
When I double-click on the winsum-1.0.4 file in the Plugins folder, I get the message:
"Invalid or corrupt jar file C:Program FilesExpert Lottopluginswinsum-1.0.4.jar"
Could you please help me with that problem?
Best Regards
Jerzy
