Did you even try what I said? You can make it run the game and trainer AS ADMINISTRATOR even when logged in as another user. You will not have to start over.
I believe what he is saying is that when he starts the game and trainer in administrator mode, the game can no longer access his save file (due to permission errors).
If you can locate your save game file try this:
1. Open Command Prompt with Administrator Privileges
2. Navigate to the directory with your save game using cd command.
3. Type this command: TAKEOWN /F *.*
4. Type this command: ICACLS *.* /grant administrators:F
5. Type this command: ICACLS *.* /grant [COMPUTER NAME]\[WINDOWS USERNAME]:F
Make sure to use the correct information in step 5 (you can find both typing the command "whoami" in Command Prompt.)
