I am having problems trying to re-install WiFi Companion to my x51v. The trouble comes when I try to use my Registration key to register the product. The first time I installed WiFi Companion to my x51v, the registration key worked smoothly. No problems.
However, just recently I had to do a hard reset to my x51v (yeah I know...it sucked) and then re-instal all my programs. (I know I should have back up'd, but I am new to the PPC. Now I do use Spb Backup). Anyways, all my other programs re-installed and registered perfectly fine with their registration keys I had from before, with exception of WiFi Companion. I re-install WiFi Companion and I plug in the registration key...but I get an error message saying that the key was incorrect! Why???
I tried to re-activate my software on the Socket website in order to get a new registration key...but it said the product # i used was already registered. (I know that because I'm the one who registered it before.
So now I'm stuck. I can't get a new registration key and the registration key I have does not work anymore. What is going on? I can't get any help from Socket's support menu.
Does anyone have any idea what is going on here? I really like WiFi Companion and I want to continue to use....but I don't want to pay for it again.
I would really appreciate any help you can give me.
