VPI Support

Hello everyone. I am new not only but to the VPI family as well. I bought a b-stock scout last January, and for a while I've been having a problem with records skipping. Now, this does not happens from the get go: sometimes I can listen a full album without having any problems. Maybe two, but by the third it starts skipping. I've checked VTA and VTF everything is as originally set (though i've made the whole setting at least 10 times by now). The last adjustment i did (today as a matter of fact) was to the arm lifter height. Yet I had the same problem by the second album. Anyone knows what the problem might actually be?

Any help will be immensely appreciated.

Javier Santiago-Lucerna.
