UM175 aircard-cannot get signal. red flag in signal area

[srtjm30]

My aircard was working fine, then suddenly stopped.  Now will not pick up any signal, and in the signal area has a red flag.  The Connect WWAN and Start VPN are grayed out and when I try and activate is just fails.  I have uninstalled drivers and VZacces and reinstalled.  Also have tried different PC.  Any ideas?  Verizon says, my card is activated.
