After pondering the description of the problem, have you made certain that the drive letter that each Adagio workstation uses to access the Adagio programs is identical, even for the session that is actually running on the server? After making sure that this is the case, re-install the BankRec Upgrade and see if it fixes anything.

As discussed some time ago, the C:\windows\crystal folder needed to be copied to the \%UserPROFILE%\windows\crystal folder to allow this to work in Terminal Services.

This will be done automatically for you if you are using Adagio BankRec 8.1C (2011.11.08) or later. This is from the release notes and the readme for this release:

BankRec 8.1C was updated from version 7 to version 8.5 of the Crystal Reports print engine. When installing Adagio for use with Remote Desktop Services (Terminal Services in Windows Server 2008 and previous versions), this necessitated manually copying the crystal folder from the main windows folder to the windows under each user. For example, on Server 2003 you had to copy the crystal folder from C:\windows\ to C:\Documents and Settings\username\windows. This is no longer required. The install and workstation installs will do the copy. The BankRec program will also do the copy if possible, which will avoid the need to do a workstation install in some cases.
