ADODB Connection Error

I have been struggling with the error below off and on for a couple of weeks.

OPM V8i SS6 08.11.11.316

PW CE 10.00.03.167

64 Bit Access Database Engine

Data Manager V8i SS8

I click OK, the model continues to open however no line sizes are available for selection.

  

**EDIT**

Randomly the Project Wise login appears while still in a session of OP. I log in, the model exits and then am forced to free it.

If anyone needs any further information please advise.
