Returning user needs help updating older models with obsolete parts

[Bob G]

Hey guys, I could use some help. I've been away from LDraw and LDCad for quite some time, and decided to get back into it. I downloaded the latest parts libraries and tried opening my old .ldr files, and every single part is showing up as obsolete, with a white bounding box outlining each part in the model. Rather than have to manually go in and update every single piece with their updated files by hand, is there a script or something for LDCad which will automatically update my old models?
