The server might inject ads into non-zip files, or files with unknown extensions.
7z just compresses better sometimes.

.zip versions of the files should be up now.
core.zip was updated

1. extract core.zip (just overwrite, if appropriate)
2. extract all other files into folder _dd1 (dir from core.zip)
3. optionally modify ack.bat so the path points to the location of acknex.exe
4a. double click ack.bat if step 3 was used
4b. else: load main1.wdl into SED, make SED point to it, and execute

version A6.60 only
Should work on Win98 with modified .dll.
Don't expect a lot.
