I just moved my site to another host  server and have new IP adress ... then discovered this error when upload  any module:

Failure

ExceptionICSharpCode.SharpZipLib.ZipException: EOF in header at ICSharpCode.SharpZipLib.Zip.ZipInputStream.ReadLeByte() at ICSharpCode.SharpZipLib.Zip.ZipInputStream.GetNextEntry() at DotNetNuke.Modules.Admin.ResourceInstaller.PaInstaller.ReadZipStream() at DotNetNuke.Modules.Admin.ResourceInstaller.PaInstaller.Install()

I checked that I have full read and write permissions to all Rootfolder... Can anyone tell me whre else to check what  the error is ?

Thanks in advance
