I have been along time(paid)user of WinRAR. If I install the beta version will I be charged when it becomes a full version? If I'd rather keep v. 3.93 will it be possible to reinstall 3.93 if I don't wish to have v4.xx on my machine? History tells me I may be stuck with something I may not want to upgrade to without using an archive back-up for one program? Jeff
