Problem: Download Graph from WebAccess Icon does not work. Graphics and scripts not update.
Possible Causes:
1. UNDERSCORE used in Project Name.
WebAccess appends the ProjectName_NodeName using and underscore. If you use an underscore in the Project name, WebAccess gets confused and will interpret the characters before the underscore (_) as the project name.
2. Remote Access Code mismatch. This occurs frequently when WebAccess is reinstalled and either an incorrect or no remote Access code was entered the second time.
Solution:
1. Rename Your Project.
2. Re-install WebAccess with correct remote access code. This is recommended if you have many users using this SCADA node to save time in notifying them all.
Alternatively, use update to update your project to match the new remote access code entered during the install. This might be faster if you are the only user.
