Just received and installed Guide 9.1. Transferred the UCAC4 data (z001 to z900) from DVD to a file D:\UCAC4. Downloaded the tdf to point to that folder. Also put a pointer to that file in Guide.dat. Toggled UCAC4 on in Extras.

Having done all that I don't see anything that looks like UCAC4 data when I click on a star. I confirmed that the star was in the UCAC4 catalogue via Vizier.

Learned a lot about Permissions though!!!
