Hi,
A time ago, ChaosGroup released a newer version -
Update 1 hotfix 1, which is supported by the ForestPack 6.1.5 / 6.1.6. Please download it from the
ChaosGroup's Downloads site & install this update, which should fix it.
If there will be anything more we can help you with, please let us know. Have a nice day.
Best regards,
