so, I've been having horrible lag issues mostly just in raids, which is mostly what I do these days. So I erase a bunch of **** from my HD and de-frag. I'm not really a computor person or really know all the ins and outs like allot of folks do. So, when I defrag there are a bunch of ddo files that can't be defragmented. So I'm wondering if I should just reinstall DDO or not, and if I should, since I bought the game online from turbine and hence have no hard disc copy where can I get it to reinstall? Thanks in advance
