Recently, I've come across a serious issue with my FSX. I haven't used the sim for a couple of months but now when I launch FSX, there's an "Online Activation" window that pops up. I purchased they 737 - 600/700 & 800/900. When I enter the key for my 600/700, it gives me some weird error message then crashes my client. If anybody can share some knowledge, it would be greatly appreciated. I need this issue to be resolved. You can look at the screenshots below to get a better idea of what I'm experiencing. Initial Launch - Online Activation Popup After I enter my product license key, I get this error. When i cancel the activation windiw, I get this.
