Stupid application wont start memory error.

just random venting into interwebz bout random crap. like normal. first time ever...

click the shortcut to the launcher. Get some error about the pvp.net launcher wont work, and then something about memory was written to somewhere and couldnt be read or accessed program crash failure blah blah blah. Try again same thing, Reboot computer same things. Went to the folder to find some way to do a repair due to not being able to get the program started to do a repair from the program launcher itself. noticed a 2nd launcher labled 'admin'. Tried it. it worked. Decided that i'd close out and try the normal one again. It worked. riot sure is keeping me on my toes. :) god. god god. arggggggggggggggg.
