wireless mouse purchased this Jan from amazon and site says serial number not recognized

[DeborahCliburn]

I purchased a wireless mouse from amazon hp store this year.  It should be under warranty.  It has started losing connection all the time.  I replace the battery with no luck.  When I get on HP site it doesn't recognize the serial number so unable to go any further.  How do I get help on this?  Also have already downloaded the diagnostic package only to be told it won't install on my laptop.

I also tried to download the diagnostics package to check it but I get a message saying it won't work on non hp hardware.  I don't have a hp laptop
