I wanted to access the CTA5 online manual but found it was not available. I tried the CTA4 and had similar experience. I wanted to know how to import ctprops created in CTA4 into my current stack of props. Naturally, this lack of access is happening outside the Mon-Fri support window. Hence I suggest you make a PDF User Manual available for download. You can add a password if making it available widely not to be in your interest, but at least registered users should not be left out in the cold when there is a technical or update glitch accessing the online manual.
