Hello Crystal,
I'm also running Win7 64-bit OS and have been using the 32-bit flash driver without any issues. Adobe is supposedly working on a 64-bit flash driver, although they haven't released it yet.
To ensure a clean installation, I would recommend uninstalling whatever version of flash that you downloaded before, then start from the beginning -
You can download the current version of flash here ..

Free McAfee Security Scan Plus"
After you finish installing it, make sure it is up to date by visiting this link ..
