After Successfully Goatbreaking: Connection being rejected by TKFE AND PC Studio

Edit:
PC Studio (after rebooting the phone and my computer several thousand times) accepts the phone once more.

However, TKFE is as immovable as ever.

"Error: Communication link is lost."

I think it was Agoattamer's TKFE link that I saw it written, but a moderator said something to the effect of "after the first time in TKFE, re-establishing a connection should be no problem."

Edit: Yeah. It was. (http://www.samsung-impression.org/samsung-impression-help-desk/dedicated-tk-file-explorer-tkfe-problems-and-hints/)

I understand that the program is buggy, though, what with the whole "reboot the program" thing when it's overtaxed. It freaked me out, though, when, at one point, I was given the choice to select between COM 3 AND COM 4 while just having my one phone plugged in.

I just need some resolution!

Thanks!

(Note also: I deleted TKFE from my computer and then re-downloaded it to try using it "freshly." Rebooting the computer and phone several times were similarly on my list of attempted fixes.)

Yeah, I'm sure PC Studio is off/not running/disconnected.
Still, the problem persists, I can't connect to TKFE.
 

You've done it again, my friend! 
Thanks!

(Shutting the phone off worked).

Connection's still erratic, but better than nothing

We have a sticky all about TKFE in the Help Desk section.  And rebooting the phone is in it.  It pays to search and read the stickies. 

Why not use BlueFTP after using TKFE once to install it?

blueFTP is an app that once installed via tkfe allows you to add games and apps to your phone from your SD card. Check it out here

Definitely less buggy.
