Visual C++ Runtime Error!

[dlpirl]

I am running nLite 1.4.6 on XP Pro SP3 and get the error message "Visual C++ Runtime Error! R6025 - pure virtual function call" just as I begin the integration process, adding multiple drivers from a decompressed DriverPacks folder to my XP Pro SP2 installation files. I have had this occur twice. nLite closes after clicking on the error message dialog. See the attachment.

Update; I don't know what was causing that error, but now before running nLite, I slipstreamed SP3 into XP2 using the /integrate switch, and nLite seems to work fine on that as long as I add the DPs drivers a chunk at a time (C,CPU,G,L,M,S) and not all at once.
