I resolved the problem with the following steps:
Created a new project with a new analysis.
Copied all items (by lassoing all files and links) from existing analysis
Pasted in new analysis (losing all layout)
Generated analysis.
Closed old analysis.
Copied liason.* from new to old.
Opened old analysis and layout preserved.
Able to add link.
Maybe there is a better way but it worked.
