Hi
In the VP "Options" section you can set the location for the Cache file. Note where you have it at present in case you want to move it back, then set it go on the desktop. Depending on how your computer is set up however, the VP cache file may be "Hidden" so if you can't see it on the desktop when you have made this change. If this is the case then you will have to alter the properties of files and folders to show "Hidden" files.
Once you see it, you can open it and confirm that you have indeed got data in there.
(If you don't like this idea of having all "Hidden" files visible then click the cache folder icon and under properties un-flag "Hidden" and then go back to the Files and Folders properties and reset the general flag.
If you are running version 3 then file types in the cache are all .CACHE. In earlier versions the files had different type designations. If you are going to revert to an earlier version of VP then it's best to remove all NCH files and folders (including the cache file) before re-running the vpsetup.exe for the earlier version.
