***SEVERE ERROR*** HELP URGENTLY

Hello, And first off i'd like to thank you for reading my post. So, Onto the problem. About a week ago my server was running normally, then i reloaded it because it was laggy, Later, Every time i logged off and on it just set my player back to the spawn! It only does that for me! So i thought my player file was corrupted and im kinda correct. I try to open my [austin.1346.dat] in the [world] file for my server. When I try to open my .dat doc it says for notepad: Access Denied! Wordpad: Failed to open document! I can open up other players just fine!
Yes, i am administrator on my computer and have opened the same file before. The thing is i can't open up my own .bat in the [world] file! It acts like I'm a new player, I get the violet/pink welcome message and others don't! it completely resets my inventory and my /gm and /god. Idk WTF is wrong with it but its making me angry! Please help!
Thanks in advance- austin

 

try restarting your server.

 

I have restarted it TONS of times! Thanks for helping though.

 

Didnt you try to delete your .dat file?? And let it generate a new one?

 

It's fixed now, i just had to restart my system, but yes, it said i didnt have access to delete it or do anything to it whatsoever. Thx anyway!
