Any luck solving this? About a week ago I updated to 1076 and got those same errors, my only solution was to revert back to 1065 since 1075 is no longer available. Problem now is Draw Sprite is not in 1065, so need to find a way to get 1076 to work. Using Tier 2 in VS2010 on WinXP.
Also, Tier 1 was working fine with 1076, just Tier 2 gave me those errors.
EDIT: Just re-installed 1076, no longer getting the "one or more point sprite functions were not found." error, but both Tier 1 and Tier 2 have the other GLFrameBufferExt error. For now this will be good since at least the sprites work this time.
