[molpro-user] problem in caspt2

[KhanBasir Ahamed (자연과학부)]

Dear Molpro-users,
I would like to calculate the CASPT2 of a ion-molecule complex.
Let say, my system comprises with benzene and proton (C6H6,p) like as:

But it shows error. For your convenience I copied and paste the last portion of output file.
I would be glad if anyone can help for this problem.
