I have tried multiple times to update my Blackberry Desktop software from 4.7 version to 5.0 and have not been successful. I removed the version 4.7 as instructed, then downloaded the 5.0 software from the Verizon site. I keep getting an error message that says ..."zip damaged: file. Bad CRC 7b2963ee (should be cd5032f4). Possible cause: file transfer error." I re-downloaded at least 3 times and tried to install, but the file would not unzip and I continue to get the same error message. I would like to update my BB storm to the 5.0 OS but wanted to upgrade my desktop software first. Is there anyone who can tell me what I need to do to make this work?
