Why is this happening with my adobe after effects?

Help me please,
Does anyone know and have this kind of problem and how to fix it? I tried also re-installing the software but still the error occurs. It happens when i try to import footage. Before it was fine but now is kind of annoying. Thanks for your help in advance.

After Effects error: sorry, the last command could not be completed (-1700).
