DCharts Download does not work

Hello,
I’m getting following exception while trying to download chart:
java.lang.NoSuchMethodError: org.apache.commons.codec.binary.Base64.decodeBase64(Ljava/lang/String;)
I know that is connected to apache common codec, and I was changing lib version from 1.9 - 1.3 but it didn’t help.
Thank you in advance for help.
