Hey, I've checked the warez thingy... According to the filenames, 6.20 and 6.22 are all warez versions. But they are kinda obsolete now, right? I mean with 6.40 out, new commands that the 6.20 Acknex can't handle... Imagine someone overwriting 6.20's template files with the trial's I can imagine how angry they would get.
How old is 6.22? I remember there was like an update crisis on A6...I bet its pretty old...
