I am new for GhostDoc, and I've tried GhostDoc enterprise trail version on my local machine to ensure that it meets my requirements (I have downloaded just two days before). Currently I'm using bamboo as build server. So I thought I just have to install/configure GhostDoc under the bamboo in order to use the command line version to build the documentation. For that I have place all the GhostDoc supporting files in bit-bucket repository and execute the below command by calling the same repository. Unfortunately this does not work. The console output always tells me that the evaluation period has expired: 

Script: 
cd ${bamboo.build.working.directory}\GhostDoc

SubMain.GhostDoc.Cmd.exe /solution:"${bamboo.build.working.directory}\Sample\Sample.sln" /helpConfiguration:"HelpFile" /projectconfiguration:"Release"

Error details - * Evaluation period has expired.

Please help me on this. Once creation of help doc will successful, then I am planning to go with licences version.
