Need help with T-Mobile Digits uninstall leaving problems on my comput

I installed T-Mobile's "Digits" program on my W10 Pro PC (updated to the most recent release), decided i didn't like it, then ran the uninstall. I am now left with the attached JavaScript error every time i start the computer.

Can anyone guide me on how to get rid of it?

I tried T-Mobile support, but after several chat sessions, being called by them, being transferred to tech support, then being left to die on hold for over an hour (by my phone's timer) having to listen to horrid music and two worthless messages repeated over and over, i hung up, leaving a request to be called by a supervisor in a third chat session that was never picked up by a human. Just as a side note, in my prior experience in roughly 30 YEARS with Verizon (i previously was with Cellular One and it was one of the companies merged when Verizon was created), i never had such lousy customer service...

Many thanks spunk!

Though Geek Uninstaller didn't have it, i then used a combination of your advice (to blow away that folder) and i ran regedit, deleting every reference to "digits" that was in the proximity of t-mobile or tmobile.

I appreciate your help very much!

I changed over to T-Mobile from decades with Verizon as their cost was very attractive and a few people i know said their service was acceptable, but as the old adage goes, you get what you pay for...
