Pantech uml290 error

Pantech uml290 My verizon (VZAccess Manager) asked me if I wanted my updates, so I proceeded with the updates.  Every since that time my air card gives me an error code of 2101 when I try to log on.  I have to restart my computer each time to get it to work.  Im not sure what the code means or how to fix it.  Please advise if you have come across this before or if you know how to fix it.  Thanks
