I had posted this in
minelli's thread last year, and I feel it bears repeating: if you don't want to deal with the nag screen, you can use
7-Zip, which is freeware.
If you install 7-Zip to its' default location, just change step 4 in minelli's list so that the command is either:
"C:\Program Files\7-Zip\7z.exe" u LEAGUEFILE.zip -up1q1r2x1y2z1w2 -x!*.zip,*.bat -tzip
or
"C:\Program Files\7-Zip\7z.exe" u LEAGUEFILE.7z -up1q1r2x1y2z1w2 -x!*.zip,*.bat,*.7z -t7z -ms=off
The first version will create a ZIP archive, the second will create a 7Z archive - ZIPs are more universal, 7Z offeres better compression (although it is a bit slower).
