After checking the issue, it seems this is a general ACT related issue. As this forum focuses on Windows 7 specific issues, this inquiry would best be posted to ACT forum:

The reason why we recommend posting appropriately is you will get the most qualified pool of respondents, and other partners who read the forums regularly can either share their knowledge or learn from your interaction with us. Thank you for your understanding.
