just got this error message while running my app on the device. Never got it before. Lexical or preprocessor Issue: "BT_downloader.h" file not found It points to a code line in the appname.appdelegate.m file: #import "BT_downloader.h" but seems there isn't any file with that name.. The only big change I made it was to change the image called BgRefresh.png located in BT_image -> Gui.. I just change the picture, leaving the same file name and extension, so seems weird that this two topics are related, but still I think it was worth to mention..

Have you tried re-downloading the Buzztouch app from the site to see if it was not an error with the download ?
