Morning Amir.
the image you have uploaded "http://answers.ea.com/ea/attachments/ea/star-wars-the-old-republic-en/25270/1/19.PNG" appears to be of a folder containing "Short Cuts".
The are not really game files but more of a redirection to the game files.
If you Right Click the "Star Wars - The Old Republic" icon in the top of your picture , you should have the option to "OPEN FILE LOCATION".
That will take you to where your Game Files are actually stored on your PC.
*When trying to facilitate the level of repair that your game files appear to need, it will require that you delete specific files within your Game's Directory/folder.
Nothing will be damaged by the process as the 'Launcher' will re-generate many of the files instantly upon the next time you load up your game.
I'm Currently enjoying my morning coffee so I will type out a few of the things that you will have to do; USER BEWARE... First Coffee of the day comes with 'Some Risk".
1: Lets go to your ACTUAL SWTOR INSTALL FOLDER; Right click the Short Cut and select 'OPEN FILE LOCATION'.
*If your PC does not give you that option when you right click the 'Short Cut' (Which is illustrated by having the Swtor Icon and a arrow in the bottom Left Corner of the Icon. You can Select Properties down the bottom instead.
**Here you will see(on the Shortcut Tab) 'Start in" which will contain the line simular to this ""C:\Program Files (x86)\Electronic Arts\BioWare\Star Wars - The Old Republic"
This is where Swtor is installed on my/this computer.
***You may have an "Open File Location" button on the bottom of this tab, depending on your version of Windows.
2: Now that you are in your Swtor folder and you can see all the files and subfolders eg: "brwc_swtor.exe" "launcherDiag.exe" and another folder within your Star Wars - The Old Repupublic folder called 'Swtor'.
Open that folder ("Swtor") ... you will now see a folder called "retailclient" and a file called "DiskCacheArena".
We wish to Left Click "DiskCacheArena" and then click the Delete Key on your board.
*don't stress the game will make it again when you reload the game.
3: Now click the up/back arrow so that we are back in the main folder of your Star Wars the Old Republic directory.
At the top you will see a Folder Called "bitraider"; we wish to delete that also.
Now you should be able to run your Launcher (*Start your game like you Normally would) and it will automatically do a repair.
I can only hope that you have a better time of sorting your game this morning with this information.. if not please feel free to reach back out.
Enjoy your day.
