STADD Integrated RAM connection Error


Please note that I am using STADD integrated RAM connection in one of Tech structure design as per IS 800 code, however after design of connections for eg. BCF, BCW etc in STADD file and after making few changes in STADD file I am not able to open that STADD Integrated connections again as STADD is crashing frequently.

Cant we edit the STADD file after connections are designed? Is there way/procedure to make new version of STADD file so that connection design can be retained with STADD crashing?

Do advise.
