i have been succeed in solving the readprocessmemory_error problem.(xp2, windows media player 10, FairUse4WM 1.3 Fix-2)

1.use windows media player 10, not 11.
if you use 11 now, you can follow the steps:

(1). uninstall wmp 11 (control panel, add/remove programs, windows components)
(2). uninstall wmp 11 runtime (control panel, add/remove programs)
(3). uninstall Microsoft User-Mode Driver Frameworks (control panel, add/remove programs). if the Wudf01000 confirmation box appears click OK and continue
(4). Open a command window. Click Start-->Run enter cmd and hit enter.
(5). change directories: cd \doc*\all* <--puts you in \Documents and Settings\All Users
(6). remove unwanted attributes from the DRM directory: attrib -s -h DRM
(7). Open Windows Explorer, navigate to \Documents and Settings\All Users and then delete the DRM directory
(8). go to microsoft.com/download and get wmp 10
(9). install wmp 10

2.upgrade your drm at:
