Thank you very much everyone for your replies and suggestions, I tried all three options to be safe and discovered that it was my SweetFx version that caused the problem for me, so it is sorted now! PS. Sorry Ron, do not ​understand what wrong with so, English is not my first language, I have to keep looking for translation and asking a friend for help to build the sentences so it takes me some time. Glad you were able to understand what I wrote however! Thanks again everyone for your help.​

So the other day I was flying around normally when I experienced the old out of memory error and I had to close FSX. This struck me as odd as I've only had this issue in DX9 mode, which is why I bought the DX10 Fixer and have been using the DX10 Preview. So I assumed I must have accidentally turned the preview mode off in the setting and when I went to check, I don't even have the Preview DX10 button there anymore! I have the acceleration pack installed so I know it should be there and it has been as I've been using it! I've tried repairing my install using the discs, reinstalling directx, rolling back my drivers incase an update caused a problem and nothing has helped. Has anyone else experienced this or have any suggestions as to what may be causing the issue? Thanks, Matt
