Funny thing: again many comments concerning password problems ;) For newcomers & MAC users - please read below & find (hopefully) the solution for pass problems (thanks to anonymous friends posts in comments):
It seems like the trouble is that the files dont work with the "Stuff it expander" applikation on mac os x.Instead use the applikation UnRarX (download at http://unrarx.sourceforge.net/ ) and it will work.(dont forget to first write the password before you drag n´drop the file in UnRarX window.Yes, the problem is not copying the passwords correctly (which everyone seems to be doing) but rather the various unstuffing programs incompatibility with the encrypted files - especially mac osx's apps and older versions of stuffit.
Sorry, guys, this problem was requested, discussed & solved several times here! I simply can't understand why using standard WinRar programm causes so many problems. Hopefully this post will solve the problem again.
P.S.: I will continue with passwords for obvious reasons ;)
P.P.S.: Thank you for all the friends posting comments here! Silent friends - don't be shy - looking forward for your feedback!
