downloading error

Hi,This morning I was trying to download CESM 1_2_0 as usually but I got the error message as "svn: REPORT of '/!svn/vcc/default': Could not read chunk delimiter: Secure connection truncated (https://svn-ccsm-release.cgd.ucar.edu)" can someone tell me what was happening and how can I download the software? thanks, 
 
CESM release code will be made available through a Subversion repository. Access to the code will require Subversion client software in place that is compatible with our Subversion server software, such as a recent version of the command line client, svn.Currently, server software is at version 1.6.11. According to the information onthe Subversion FAQ it should be ok to use a client at version 1.5 or later.With a valid svn client installed on the machine where CESM1 will be built and run, the user may download the latest version of the release code. First view the available release versions with the following command:> svn list https://svn-ccsm-release.cgd.ucar.edu/model_versionsWhen contacting the Subversion server for the first time, the following certificate message will likely be generated:Error validating server certificate for ’https://svn-ccsm-release.cgd.ucar.edu:443’- The certificate is not issued by a trusted authority.Use the fingerprint to validate the certificate manually!- The certificate hostname does not match.- The certificate has expired.Certificate information:- Hostname: localhost.localdomain- Valid: from Feb 20 23:32:25 2008 GMT until Feb 19 23:32:25 2009 GMT- Issuer: SomeOrganizationalUnit, SomeOrganization, SomeCity, SomeState, --- Fingerprint: 86:01:bb:a4:4a:e8:4d:8b:e1:f1:01:dc:60:b9:96:22:67:a4:49:ff(R)eject, accept (t)emporarily or accept (p)ermanently?After accepting the certificate, the repository will request a username and password. Be aware that the request may set current machine login id as the default username. Once correctly entered, the username and password will be cached in a protected subdirectory of the user’s home directory so that repeated entry of this information will not required for a given machine.The release tags should follow a recognizable naming pattern, and they can be checked out from the central source repository into a local sandbox directory. The following example shows how to checkout model version cesm1.0:> svn co https://svn-ccsm-release.cgd.ucar.edu/model_versions/cesm1_0 cesm1_0 This will create a directory called cesm1_0 that can be used to modify, build, and run the model. The following Subversion subcommands can be executed in the working sandbox directory.For various information regarding the release version checked out...> svn infoFor a listing of files that have changed since checkout...> svn statusFor a description of the changes made to the working copy...> svn diff Essay writing company reviews
