VPN ASA 5505 8.3 (1) to ASA 8.2 (2) works only one way

Just wonder if somebody could help me. I’ve set VPN up between two sites using Cisco ASA 5505 and Wizard. Unfortunately VPN works only one way From 8.2 (2) to 8.3 (1) and after spending one day trying to resolve the issue decided to ask somebody better than me. Logs shows that ping leave ASA 8.3 but never hits ASA 8.2 – opposite way everything works perfectly.
I would really appreciate if somebody could advise me something.
