Yes don't worry. If it's not a game bug a solution will be found. So, are you sure it doen't say GDI Generic anywhere in the log?
I suspect your AMD graphics card drivers may be corrupted or not properly installed. I have a small guide
HERE to do a clean reinstallation of your drivers, Question 3. At step 4, download your
latest AMD drivers.
UPDATE: Yes, I just saw your edit and your drivers must be corrupted. Your graphics card should support the latest OpenGL 4.3 version and not just 1.20. Unless they changed the log to mention something else under version which I highly doubt so make sure your follow the small guide above.
