I've tried reinstalling Windows several times, however this hasnt' fixed it...
As I'm running a Home Premium, there's no way for me to access the built in administrator account thingy...
Running the sfc/scannow function did not locate/ identify any problems.
When running as administrator, I'm still unable to save any type of files.
Also, I believe this issue only occured after installing Bitdefender 2011 as I was able to successfully download the installation files for both bitdefender and firefox.
Would be really grateful if anyone could help!
Edit: When i try saving a file, the "save as" dialogue box comes up, however when I hit the save button I get the message "The file name is not valid"
