Recommend to start with a fresh version of Live, Max and PULL. It sounds like there is some serious problem with one of your installations, as this should not be happening.
Try using first without the Sigabort fix, and then install the fix once everything is working.
Install Live 9.1.7
Install Max 7
Install PULL v2.2
Go to the PULL v2.2 zip file, extract all the files and drag the PULL v2.2.amxd into your Live Set.
Then set up your Lemur to connect to the amxd
