Fatal Error on Admin Login Attempt

[tishost]

Version:
1.3.7 (can't verify..can't login to double-check.)

On admin login:
Fatal error: Call to a member function Execute() on a non-object in /home/dinostar/public_html/shop/includes/functions/sessions.php on line 61

On regular pages:
Fatal error: Call to a member function Execute() on a non-object in /home/dinostar/public_html/shop/includes/functions/sessions.php on line 61

I believe this started happening after a server move (Unix Cpanel/WHM Fantasico installl). This is a client install so I'm not 100% up to speed..just need suggestions on a fix.

Thanks in advance,

Thanks....I was actually checking thru those as you replied...didn't find an exact answer but did try just overwriting the sessions file with one from a new download and that seems to have worked.
