well, i know your autologon regtweak won't work. what you should do on your own, if no one get's here first.... eliminate the possibilities. remove all instances of execution, so remove everything from cmdlines.txt. See if your SVCPACK.INF works. if it does, add a line in cmdlines.txt. Do so untill you find the culprit. If it's somewhere in RunOnce for some god awful reason, comment out each section with REM and do the same process.
