Hello, I seem to be having trouble with security and my adobe reader! my dell lap top, when I try to access them,say's it cannot open these files, this is driing me crazy! I can't seem to get any help from Dell ,however if I pay them £55 they will sort it out. I have only had the lap top about 6 weeks and i am new to computering. I think they should give beginners all the help they need. If I knew then what I know now I would of purchased my lap top else where.
