Loading Error and temp Fix

When loading R4 it would freeze about 3/4 the way into the load. What i tired and it worked was i put the "exe" in Windows2000 compatibility mode. my system specs as follows.
WinXP pro / 2.4c P4 / 512x2 of Geil DDR3200 Duel Channel / GeForceFX 5900 128mb / Seagate 120gig SerialATA / running the 45.23 dets / and that is all you should need to know.
