Thanks. It's important to know what version of Chilkat you're using, which is why posting the contents of the LastErrorText is important -- and posting the entire contents of the LastErrorText is important to see the version of Chilkat and other context such as operating system and programming language..

If using an old version of Chilkat, test with the latest version...
