bought cursorxp plus 1.31
From where, thru Stardock who created it, it was replaced long ago by CursorFX. AFAIK CursorXP can not be purchased thru Stardock anymore.
If you bought elsewhere sorry to say but you may have paid for a cracked version.
Edit; just found an old website link on my start menu from when I used XP before upgrading to FX, link took me to the CursorFX page.
Edit2; just checked Impulse, Stardock's download manager/installer. I still show a reg. for CursorXP as I had purchased in the past but it is no longer available to be downloaded and installed, it does not show in Impulse at all.
Again, sorry but you may have paid for an illegal/cracked version.
