T-racks problem...large buffer size?

[guy.fi]

I've been using T-racks for years now with now problem (since IK fixed bugs three or four years ago)...until a few nights ago. I started having 7401 errors almost every time I opened the eq to adjust (already on the session). When these errors occured the computer would freeze and I would have to manually restart it or the session would close improperly. I uninstalled and reinstalled the plugin, to no avail. Finally I realized that I was working at 1024 buffer, which I almost never do so I changed it and I think it stopped happpening thought this was at 4 am going on no sleep so the exact order of details is a little fuzzy.

I haven't installed any new plugin for a while, Massey a few months ago but I haven't had any problems with them that I'm aware of (great plug in BTW).
