need help - from Barcelona to Torla

Hello.

I read a few topics in this forum about reaching Torla, they all telling go from Sabiñánigo to Torla with Alosa. But there is no such bus right now. I need in 14 Aguste.

So i found a few possibilities.

1) From Barcelona to Barbasto by Bus. Then from there to Torla. Both with Alosa. But the problem is that between buses is 15 minutes, and there is no another buses until 19 in the next day. So if the first bus late in some reason i will stuck there for to much time.

2) Another option is Train from Barcelona to Lleida. Then bus from Lleida to Barbastro. And then again form Barbastro to Torla.
The main problem, were is the bus station in Lleida? In the Alosa web page no information.
And this option is much more expensive and complex.

So my questions is:
a) Were is the bus station in Lleida for bus Lleida-Barbastro?
b) Is there another options?
I will be in the airport of Barcelona in 14 Aguste in 9:00 and need to reach Torla in the same day.

Thank you very much and sorry about my bad English.
