Yeah that kind of doesn't work at all. You didn't specify any sort of directories for that so unless the batch file is actually in the same folder as your UID then it is not going to do anything. Also judging from what I've read on here the UID can only be written to file_store_32 or jagex_cache_32.
You could just use this one that I made up a couple days ago. Just save this as a batch file then replace your shortcut to SCAR with a shortcut to this. This'll delete your UID before you start your autoing session and after you finish your autoing session. Not much room for you to foul up and get your main associated with your autoers.
echo off
cd C:WINDOWS.jagex_cache_32
del uid.dat
cd C:WINDOWS.file_store_32
del uid.dat
cd C:Program FilesSCAR 2.03
start scar.exe
echo =============================
echo PRESS ENTER WHEN DONE AUTOING
echo =============================
pause
cd C:WINDOWS.jagex_cache_32
del uid.dat
cd C:WINDOWS.file_store_32
del uid.dat
or for a less fanciful approach simply
del C:WINDOWS.jagex_cache_32uid.dat
del C:WINDOWS.file_store_32uid.dat
Also while I'm at it why is it that So few people have bothered to read my thread in Strategical info and even fewer have posted on it? It is actually worth reading and discussing a tiny bit folks. If for no other reason than to tell me that I'm wrong or confirm that I'm right. Here be a
link.
