Unable to reverse system restore

[proton]

I'm using windows XP and I'm trying to reverse the system restore I just did. I've tried undoing it, but my comp just keeps saying its unable to undo the system restore. What do I do?

I think safe mode system restores can't be undone, but otherwise undoing after system restore should be "available" (it complains at the very moment when you start doing the undo - procedure?) ... is there anything else in the error message, or anything more in system event log?

it complains after the computer restarts. I don't remember what else it said in the error message. I didnt use safe mode restore
