Hi everyone, I'm trialling Lightroom 5.7.1 and have been getting warnings about insufficient memory when attempting to export the edited file (see first attachment). I've done a bit of research on the InterWeb and found all sorts of solutions, some of which directly contradict one another i.e. one suggestion was to increase the paging file limit and another said to decrease it. Any help appreciated. PC specs also attached.

One other question, the LR trial period is about to expire and assuming I can get the memory issue sorted, I'll probably sign up for the month by month program but am unsure if I stick with just LR or get the PS/LR combo? Any thoughts?
