Hi guys, for some reason the overlay currently does not work when you install Raid Call on your computer (when you hit Shift + Tab in game) when in WoW.
Note: I'm on Windows 7 Ultimate 64 bit, so you're steps may be slightly different, but should be very similar.
Step 1: Close raidcall and locate the raidcall folder (Usually something like "C:\Program Files (x86)\RaidCall\flash\").
Step 2: Within that folder, find the file "config.xml" inside the "flash" folder. Make sure to create a backup of the file. (Worst case you might have to reinstall raidcall).
Step 3: You might not have permission to alter the file. If that's the case, here are steps to fix that. Otherwise skip to step 4.
Step 3a: Right-click the file and open the properties. Click on the "Security" tab, then click the "edit" button.
Step 3b: In the top part under "Group or user names" select the "Users" entry, and in the bottom part check the box for "Full control" in the "Allow" column.
Step 3c: Click ok, and ok again to close the properties dialog.
Step 4: Open the config.xml file in notepad or some other text editor and copy/paste the text in the spoiler below into the file.
Step 5a: Right-click the file and open the properties. Click on the "Security" tab, then click the "edit" button.
Step 5b: In the top part under "Group or user names" select the "System" entry, and in the bottom part Un-check the boxes for "Full control, Modify and Wite" in the "Allow" column.
