Altered ROM:
Viber for Android now only partially supports two of the most popular Android ROMs: MIUI and CyanogenMod 7 (CM7). However, custom ROM entails many personal tweaks which cannot be duplicated, thus cannot be tested. Our recommendations to you would be to either uninstall and reinstall Viber [try again], or to find the proper customization which works best with Viber. Of course, returning your device back to it's original settings is the best option for compatibility.  We have no way of duplicating your specific ROM settings, therefore, unfortunately,  we cannot troubleshoot devices with altered ROM.

Stay tuned!
