Hi there. My Virtue Spire doesnt seem to be feeding correctly. When there is no paint in the loader it tries to feed (as it should) but will just stop even when empty. Also when playing it doesnt keep up to the speed my 3.5 is shooting at and will just stop feeding or stary to popcorn. Ive tried new batterys but it happens still. Ive also tried different paint in regards to the popcorning issue.
