Hi James,
The problem is that the reporting controls used by OnTime (DataDynamics' ActiveReports) do not operate properly in a 64-bit environment. In our public builds we normally flag the OnTime.exe assembly as being 32-bit only so that Windows runs OnTime as a 32-bit process even when running 64-bit Windows, but for some reason when the OnTime 2008 betas were built the assembly wasn't properly flagged.
This will be fixed for the next OnTime 2008 beta/RC, but for Beta 1 and Beta 2, the only workaround is to run OnTime on a 32-bit machine or to run it inside of a VM.
