I have the same problem as Sqwall. With london_Circuit and edited vhf files and BMW_135 edited xml file. Game will stall when it is going to load the London track or BMW car. Maybe a dumb question but are you sure the uploaded repacker is the correct one?

Japamd I seem to be running into a problem with some archives with your repacker. First the IGPHASEACTIVATE.bff archive cant be repacked throwing me this error code, System.ArgumentException: Destination array was not long enough. Check destIndex and length, and the array's lower bounds. at System.A...

Sqwall/sommergemuese that is the behavior I get if I add/delete a file in the archives structure.I believe you might have a thumb file in there with the texture that is creating this error.
