And i tried to download hearthbuddy again, but it wont work with another HB and it gives error:

"There was an error authenicating your key with the server. Please try
later again or use another key.

Key is expired."

But i think its just coz i have read the gey on other HB, but what if its really "broken" or somehing?

Sorry about my bad english, but i hope you can help me !

 

Hmm, i did everything u said but nothing happens. HB still wont open .

 

Yes i did download another hearthbuddy if u mean that, and it did say "key expired" when i tried to logging with my key (i have only 1 lifetime session)... Do i need to remove my orginal hearthbuddy to get it work or? And if i remove it, can i use the key again, or is it only for 1 time...

 

Oh my god... IT WORKS DD I did donwload it again, and i noticed that stupid me was trying to use trial key on it -.-... Well i used portal to find out my real key and put it on new HB and all works fine . Thanks for ur help!
