would it make any difference that I am now playing this game on a different laptop?
I was playing the game on my own laptop which I keep up to date, I am always deleting things that I don't need or use and defragmenting it. currently I am waiting for a new battery so I am now playing the game on my sisters laptop, needless to say she is useless when it comes to looking after a computer.
deleting her browsing history, temporary internet files and cookies took ages, so did installing updates and defragmenting. doing things like this I am reminded why I look after my own laptop so much. over 12 months she has had this laptop and has never updated it once, women eh?
anyway, thanks to everyone for all your help, I really appreciate it :-)
