Error:Null Rei's minimap

[MuffinsCanMurder]

I recently installed Optifine_1.4.6_HD_U_D5 to Tekkit Lite, and this has seemingly broken the minimap that appears in the top right corner of the screen. Instead of the map, I get a error:null. The waypoints still show up, but I can't access the menu for the map and I can't do anything with the map. Is this because optifine is conflicting with Rei's minimap mod, or is it something else?

I will assume you mistyped and actually used a 1.6.4 build, not 1.4.6.

I used Optifine recently with an otherwise unmodified Tekkit 1.2.9 and it worked, so I assume there is no general incompatibility. Still, you may want to reset your Tekkit installation to eliminate all potential sources of conflict, then double-check you're actually trying with the correct version of Optifine.
