CCL: excited state TDDFT

 Hello,
I tried to calculate the second excited state of adamantane cation (opt and freq) in TDDFT ( # TD(root=2,NStates=40) b3lyp/cc-pvtz opt sym=loose). Unfortunately the calculation ended with 
 'You need to solve for more vectors in order to follow this state.'
So I set the keyword for NStates first to 10 then to 25 and finally also to 40, but the message is the same. I tried another way: From a cis calculation I wanted to get the force contants using them for the TDDFT calculation. But the cis calculation also ended with the message above (NStates=25). Is it useful to set NStates much higher or is there another way to do the TDDFT calculation?
By the way, I also tried a cis calculation (# CIS=(Root=2, NStates=40) hf/cc-pvtz opt(calcFC) freq sym=loose). This delivers the message 
 'Tx not orthogonal to T.'
 I couldn't find any solution for this problem.
 Regards,
 Markus
