I am not sure what is going on, I have been using the same program for years that you are now directing makitamark to download.

I have successfully converted many rC5 strings with this utility, but here I am trying to convert this string he posted:
0000 0073 0000 000B 0040 0020 0020 0040 0040 0020 0020 0020 0020 0040 0020 0020 0020 0020 0020 0020 0040 0040 0020 0020 0020 0CA4

and all it give me is this:
0000 0073 0000 0010 0040 0020 0020 0020 0020 0020 0020 0020 0020 0020 0020 0020 0020 00C0 0020 0020 0020 0020 0040 0040 0020 0020 0040 0040 0040 0020 0020 0020 0020 0040 0020 09B7
i am stumped as to why
