spud

hi all, hope you can help.... got a nw-e99 for crimbo and love it. it came with sonic stage 2.1. so i loaded it up...excelent good graphics, records my cds well and works like this kind of programme should.... untill yesterday. it crashers before load up finishes. i clean uninstalled it as recomended by you guys. worked once then did it again and again. so i instaled 2.3 thinking that the 2.1 version was to blame...... nope loaded once and suprise suprise, crashes again before it even loaded. i'm running xpsp2 have ad aware6 and have used the virus scan by trend micro as recomended by you also (very good programme thanks for the link!!) so no infection here. the only programme i've installed since 2.1 is object dock but thats been running for weeks now any ideas??? thanks for your time
