STAAD Connect Edition taking long time to run

I am using STAAD.Pro CONNECT Edition - Version on Windows 7 OS. I have been using SS6 previously and it used to take less than 10 mins to run for a 6 story steel structure with member design & deflection checks. After migrating to Connect edition, the same file takes over 30 mins to run with only one envelope. Everything else remains same including P-delta analysis except STAAD version. I have tried analyzing the file in my local drive. Please advise if there is any fix to this. Also, sometimes the application crashes while viewing post processing results.
