I had an issue with the latest flash update. If you're getting an r300 error, try uninstalling flash and reinstalling 11.2. That solved the problem for me. Hope it helps you out!
yes im getting the r300 error. When i go to adobes website i cant find the 11.2 version. Its only 11.3 and when i click the "older" versions, i only see 10.1, 9, and 7. Do you know where i can get a 11.2 version thats safe?
edit: i only see 11.2 for linux but not windows
