technical interference

Just wondering if others have had as much trouble with getting powerpoints to work, cd players to play through the system, computers programs to work, computers dying...etc on weekends as we have. It seems obvious it is interference from the enemy to me. The last Tres Dias weekend my computer died. A team member with two masters in computer science did every thing he knew to do and declared it a "boat anchor". A brother and I prayed over it, went to breakfast and came back to find it started right up. This has happened twice more while working on spiritual projects. Would love to hear about your experiences, Kent
