Welcome to the Forum.
If you are on a PC simply copy the OTA link and paste it into an email and send it to your device. Once your device receives the email, then you can select the link and it should perform the OTA download.
Ditto. It sounds like you were downloaded the JAD file to your computer and tried installing that with DM. It is not possible to install JAD files from desktop manager. JAD files are mainly for installing Over The Air from your BlackBerry browser.
i emailed it to my blackberry from my computer and tried downloading it and it didnt work, am i doing it correctly
