pietu, it appears part 6 unlocked of TOPO U.S. 100K (v5.01) is corrupt. Tried downloading it 4x, and every time get a CRC error. Internet here is very slow, so tried it at various times of day (varying dl speeds) with the same result.....I will go for the locked versions, but it took several days to download the unlocked archive...Winrar repair did not work.
Anyone else?
