Do a Windows search on your entire C: drive for *.rpf files, and see what you come up with. If you find any in any other folder then C:\SoftJock\RockitProDJ50\History, then something is hosed in your configuration.
If not, is the time and date set properly on your machine, as well as the locale? Rockit generates the history names by reading that from Windows.
Ok, I just searched, and I have several that are in my I:/ drive, which is my external drive. And, they are from the 4.2 version that I no longer have on this computer. What do I have to do for this? As for the time, its all set to the correct time, including Rockit.
