First off, there is a separate
support thread for the UI, this forum section is for SOE's bugs.
Then, does going linkdead mean that your game crashed? Or where you booted to the login screen?
I do not have the TFD pack, so I cannot currently test it, but I had no problem zoning into Nizara during beta using ProfitUI. This is the first I hear of a problem as well. Not to say it isn't there, but maybe someone can confirm going linkdead because of ProfitUI. Not sure what the cause could be in that case, however.
