IPS Version outdated (Snort version)

Question

Hi everyone, 
 
 i've got a firewall (SG 135 - FW: 9.506-2, Pattern: 136330) at a customers place having trouble with ips rules. 
 After looking around i found something interesting. The snort version is really different as from my home box (virtual machine, same FW and Pattern). 
 
 Snort version on SG135: Version 2.9.7.6 GRE (Build 285) 
 Snort version on VM: Version 2.9.9.0 GRE (Build 56) 
 
 Therefor rules with the "bitmask" statement will not work and causes snort just exit and start over again and again. 
 As of the default option to drop all packets when snort is not running, every connection through the firewall is not possible at this state. 
 
 So how do i manually update the snort to the actual version, or what would be the right way. 
 I currently have no phyisical acces to the firewall, as it is some hundret kilometers away. 
 
 Thanks 
 Bastian

Alright i got the solution. 
 
 Fixed the symlink in "/var/sec" that was pointing to "/var/sec/chroot-snort-2976.." into "/var/sec/chroot-snort-2990-03", rebooted the system and deactivated and activated the ips through webadmin. After this i've got the actual snort version with updated configuration to support the current ruleset.
