I often need to make maps that match the projection used on USGS topo maps and others. Many newer maps use UTM projections but older ones often use a conic projection such as Albers or Lambert. UTM and Pseudo Mercator projections work fine in Manifold 9 but I have not found a conic projection that works except for "polyconic." If I try to apply an Albers Conic or Lambert Conformal Conic nothing happens. All of these worked correctly in Manifold 8. Unfortunately, a UTM projection won't register with an Albers Conic topo map.

Details? What projection, specifically, do you want to use? Can you post an example of the original, source data?

It is possible that you are trying to apply a conic projection without setting the values of the latitude parameters -- some have center lat, others two standard lats, these should be set to the values you want, the default 0 is not going to work.
