Hi Andrizzay – Your Crash logs are showing CRC errors, what this means is that something has caused a file to be the wrong size and corrupted the installation. The first thing we want to rule out are issues on your drive.
Please do the following first to check and repair your drive:
1. Open Computer by clicking the Start button , and then clicking Computer.
2. Right-click the hard disk drive that you want to check, and then click Properties.
3. Click the Tools tab, and then, under Error-checking, click Check Now. If you are prompted for an administrator password or confirmation, type the password or provide confirmation.
4. To check for both file errors and physical errors, select both Automatically fix file system errors and Scan for and attempt recovery of bad sectors.
5. Click Start.
Depending upon the size of your hard disk, this may take several minutes. For best results, don’t use your computer for any other tasks while it’s checking for errors.
Once that is complete, Please navigate to your Documents > Guild Wars 2 folder and in there you should see a file called Local.dat. Delete this file.
Once you’ve done this please repair the client again.
Hope this helps!
