I bought a HTC mobile of the Wildfire version and install the HTC Sync 3.0 software to sync with my computer. But for some reason using HTC Sync 3.0, I cannot sync my contacts or calendar with my computer. I cannot start other application like for the image editing as well as for the videos inside my HTC mobile. The remainders of things are working fine though inside my mobile. Why is HTC sync software not syncing with my computer? How can I fix it? Any help will be appreciated.
