Hi, I reinstalled my OS today (Windows 7 64-bit) and tried to run Hearthbuddy, and it gives me this error message: I run the latest version of Hearthbuddy and CDPatcher, I installed the following necessary software: - MVS c++ - .Net Framework 4.5 - Java (don´t know if this is relevant) I´m ofcourse using my Key from the Auth Page and the "Public Auth" on CDPatcher. This is my Hearthbuddy Log: 2015-08-11 16:34:20,913 [1] INFO CustomLogger (null) - [botManager] MsBetweenTicks = 152015-08-11 16:34:28,025 [1] INFO CustomLogger (null) - Hearthbuddy [0.3.1008.181] is up to date!2015-08-11 16:34:31,539 [1] DEBUG CustomLogger (null) - Invalid product key! I´m curious because yesterday it worked on my old machine (OS). Or did I miss something? I appreciate every little help I can get. Thanks in advance Dethe
