I am assisting someone flying from the states to barcelona, then to Orense Spain. I've tried to google,which brings back options on trains. When I try to make a reservation or see a schedule it results in an error. Has anyone traveled this route? Recommendations?

You are still too far away from the travel dates to be able to buy tickets online.
The timetable is available, though. Works only in Spanish at the moment.
There are only two connections.
One day train, which leaves Barcelona at 09.20, and arrives Ourense at 21.55
And one night train/ sleeper train. Leaves Barcelona 20.20, arrives Ourense 09.02 next morning.

Thank you - yes, I did find a website that told me that I have to be 60 days out. Can you give me the website that you found this schedule on?

You can fly either Vueling or Iberia from Barcelona to Santiago de Compostela and then drive a little more than one hour to Orense.

*** Important***I also think you should look at Ourense (with the U).

If you want a schedule just look at dates available (within the 60 days) they do not change that much. From memory there is only one train that takes about 12 hours or so.
Other options other than driving.
You can also fly to Vigo and bus or train to Ourense.
There are buses between SdC and Ourense too.

Should have added the link to the bus service here in Galicia:

Do you have the train link? Much appreciated!

Sorry I never gave that as you said you had tried to make reservations already....it is www.renfe,es
