help with titainum and calendar, ThumbCal

[txter]

i did search around but i got a little too deep into this one.
heres what i need help with, (w/o doing a hard reset)... i want the titainum calendar/appointment panel to open up thumbcal.
i tried to edit it but i hit the wrong thing on accident and now im stuck. i got the thumbcal GUID and tried to copy/paste it into the appointments panel GUID think it would redirect that panel to thumbcal. well now i forgot which guid is which because both TC and appointments have the same one.
now i cant enable the stock appointments panel at all to show up my homescreen. i created a new panel and page for TC but i want the stock pix and details and cant get those to show up.
hope ya'll understand what im sayin here. im pretty good at figuring these things out and such but now im stumped.
a little help would be great....thx
