Window Anti-Trap issues

[BFox15]

I have a 1999 Range Rover 4.6 that has developed an issue with the driver's side window. Nearly every time I roll the window up, either with the automatic up, or holding the button to manually raise it, it seems like it is binding up approx 2/3 of the way up. The display says something to the effect of "LH Front Window blocked" and the window will lower several inches and stop. At this point I can hold down the button and the window will roll up, still binding up somewhat around 2/3 of the way up, and the dash display will say something about "Anti-trap off". If the window is wet it will generally go up without a problem. Does anyone have any suggestions as to what the issue is? I've priced motors, regulators, and such from Atlantic British but would like to make sure I'm not missing something common on Rovers before I drop the money on unnecessary parts. Thanks.

May be just off the track or cracked roller. Might want to carefully remove panel and inspect, a little grease (white lithium), etc.

Yeah bad roller on the window regulator.
