........... so i format my pc but just drive C no other drives and my ET was in the other drives now when i open it back my whole xp is gone i had 12K+ ...........
It may be the "jaymod bug" but you could try this:
Did you install ET on another drive, like D: or E:, but had to format C: drive? I wonder if your PunkBuster was installed on C: drive OR if the format wiped out appdata that your first installation had placed upon the C: drive.
Come to think of it, your PunkbusterA and B services may not be loading. You can open TaskManager to Services and scroll down to see if PnkBstrA is loaded. PnkBstrA should load at computer startup while PnkBstrB loads when you start ET.
Here is how it looks in Windows 7. It should be similar in all versions of Windows.
When you are next on an FA server with an admin, you can ask them to !finger you. It will show if your etkey is "working right". If your GUID is 0, it means that your XP record won't be saved by the server. If you do have an etkey file, we can help you get it working right.
If you ever re-install ET, the old etkey will be erased, so you must always save the first etkey elsewhere.
