I'm having a similar problem when attempting to export ODB++ from .brd file. It seems to break at some point and starts spitting out the error messages referring to D:\vSureSRC\ like the OP. The last few lines of the log_brd2odb_x.txt are included below. The fifth line is where this log diverges from other successful gererations of ODB++ files for our other boards.

Something happened to my board file when my computer crashed due to a graphics card failure. After DB doctoring after the crash everything appeared to work fine; constraint manager was fine, all components imported worked fine, and gerber generation went off without a problem. However, now that I try to export an ODB++ file(s) the symbols folder within the ODB++ archive is empty and this is something our contract manufacturer needs. I tried the suggestion of changing the artwork to RS274X and decimal places but to no avail ( we use this format so I actually moved it away and back to the RS274X settings)
Did anyone ever get resolution on this? Right now I'm attempting to place-replicate an entire board design from the newer failing brd file to an older file that still generates ODB++ correctly but it's not fast or perfect and we've already lost some time due to this.
Thanks for any help
