I didnt abort anything and still ended up with this error, verification thingy doesnt find any problems. Had backed up the install file but thats apparently not a valid win32 application now so i guess i'll start my 8th 10.x download :(
thanks everyone.
I slept for most of the day and then went to work, doesnt get much better than that :)
Planning to make up for it at the weekend though :drink::drink::drink:
