Hi Jason, thank you for your help.
I followed the directions given and none of the issues are resolved. I reset the workspace layout several times as well as changing it from classic to something else.
I uninstalled data bridge and design extender and deleted the wincache file several times. I also tried just installing one of the products, deleting the wincache.
Regarding the missing tag error when starting up DW - the error does not occur when all the WA software is uninstalled (and it was not there prior to my uninstaling the old versions of WA software and installing the new versions).
