Many simply accept checks sent through the mail. You only pay for the shareware that you choose to pay for - that you find worthwhile. If you download something, and you don't want to pay for it, you should just delete it from your hard drive. We list the fees for the programs on our pages so that people are aware from the beginning if the program they are downloading is free to keep, or how much it costs. But we do not collect any fees.
Some servers incorrectly deliver hqx files as text files instead of as download files.
Then your browser tries to display the encoded hqx file on your screen instead of saving it to disk. When it is done downloading, you will need to drag the .hqx file to Stuffit Expander to decode it. Sometimes the FTP sites that the KD uses are overloaded. So that the machines can cope with the traffic, the various sites set a limit to the number of consecutive connections. Unfortunately, by setting this limit it stops site maintainers connecting as well.
