It´s a common problem on Manila/Sense Weather that sometimes we can´t add our city or we get some updating problems over 3G/EDGE/GPRS/WIFI. XDA member JVH3 just updated this useful tool to fix these problems. Now, the app supports more ROMs and sports new icons, just to mention some of the new features.
Developer also points to the work done by XDA member obaz, which allows you to add a custom city using a PC. Both tools combined will let you solve most of the updating/adding problems.
