Windows does not report increased free space


New Member
Hello and thanks in advance.
I'm using on windows 7

I used the program on about 32 GB of stuff yesterday. As usual the file folders were still there but no files show in them. I went to check for free space and there was no big jump as i had expected. I deleted the folders using win explorer. reboot - no joy
Checked to see if there was an update available and got a 404 error.
On the download site I see there is a newer version but Not sure which to try. I want stability more than new features.
Confused and concerned now...
