Whether it is possible to go to Pripyat without a guide (S.T.A.L.K.E.R.: Call of Pripyat)

Caught a bug that Explorer in Pripyat is just standing there and not responding to me. Do not want to do. I have all the quests in Pripyat fulfilled, clambered the entire length and breadth. And leave can not, because he is blunt and I can't talk to him.

I just want to know if there's some other way to get out of the Pripyat? Found the well from which we climbed down and he caved in.
Don't know what to do
