Help on ERead Error in module ACQTMAPP.exe

I have had repeated trouble with my Windows 7 - this error message occurs about every 3rd time I log in:
Exception EReadError in module ACQTMAPP.exe at 0001BFCB. Error reading TrayIcon1.visible: cannot read shell notification icon.
Can someone tell me if this is a Windows error or some other program? How do I fix it?
My entire profile was lost and I now repeatedly get the error "cannot load profile service." I am terrified this profile which is the only one working now is also going to crash.
I lost all my old email and all my email addresses - about 5 years worth of information.
Rather desperate. Help please!!!
