dreamweaver MX and Vista

I have a new laptop with vista home, I installed my dreamweaver MX and it ran fine for three days, then today I went to incert a table and got an error saying " a sharing violation occured while accessing C:\Users\AppData\ roaming\Macromedia\Dreamweaver\MX\Configuration\objects\Configuration\Table.htm."
I went tot that file and made sure it was shared even though I am the only user set up on pc and problem continued. when I tried to make a table again Igot a a coruption ocured and dreamweaver needs to shut down , which it did. I uninstalled the program, reinstalled it and it worked fine for the first table and then did it again. Can anyone help with this
