We just updated to ProcessBook 18.104.22.168. We have some pdi files that are all VBA based and have no active tags on them. When we double-click on a pdi file it launches ProcessBook but we get the following error - "Run-time error -2147220314(800404a6): No current user available. Server may not have been opened." It does this for the majority of the pdis. We never get the login dialog to connect to our PI server. This worked fine in the previous version we were running (22.214.171.124). Any thoughts as to why it isn't working in 126.96.36.199?
