Ah, sounds like the old problem assocciated with mpeg codecs built into machines, i suggest a complete reset and perhaps rewire of the key electronic components in order to establish a secure and SAFE fitting of the laser.

perhaps a search on the interweb can bring up some useful guides. I myself simply call the experts in, due to having extremely expensive equipment!

Be sure to swab the laser with alcohol first to ensure a perfect fit!

regards.
