What Operating system are you using? 64 bit? service pack? - x86, WinXP Media Center Edition 2002, Service Pack 2. 3. If you have virtual drives, disable them while profiling and playing profiles. - Okay, didn't know that. 4. Uninstall Directcd, Incd, Dragtodisc, DLA or any other packet writing software you have on your system - Haven't heard of such software before, so I don't think I have any. 5. What protection does your game use? According to Protection ID: SafeDisc 1.50.020 6. What is the name of the game you're trying to run? Age of Empires II - The Conquerors 7. What is the version of the game? 1.0c 8. Is it cd or dvd version? CD 9. What region or country is the original disc from? EU 10. What cpu are you running? Intel Core2 Duo T7200 @ 2.0 GHz. 11. What optical drives (dvd-rom,cd-rom, burners) are you using to create profiles with? What firmware version is installed on your reader? Optiarc DVD-RW AD-7540A. Firmware v. 1.42 rpc1 12. What security software (firewall, antivirus) are you using? Please provide version numbers. AVG Free v. 7.5.472 13. Describe your problem, provide full error messages, and please state clearly what you were doing when you received those error messages. Ok, here goes: I was trying to create a working profile for said game, first using the game profile provided with Game Jackal, didn't work ("Please insert the correct CD-Rom" error message, the loading screen didn't show up). I tried to run the game on processor 2 only, using Game Jackal settings. Then I decided to create a profile from scratch, and after getting the same error as last time, the profile didn't have time to deactivate, I got an INVALID_KERNEL_HANDLE bluescreen. I assume you want the debug log, so I provide it zipped. From the log: "PROCESS_NAME: GameJackal.exe". I can't remember what I did to make it work on my other computer - and this game should surely be on the working game list, seeing how old the game is and as there is even a provided profile for it? Anyway, since I didn't know about disabling virtual drives until I got here (after the crash), I wouldn't have posted this if I wouldn't have gotten the BS. At least not until after trying disabling the virtual drives. But a bluescreen is a bluescreen, is a bluescreen.
