errors

Hello, my project is a RC structure building. I am working in "Building Design" in robot. My problem is that when i choose the "pinned-pinned" type of release for all my columns; during the analysis it keeps giving me warnings about instabilities(type 2) at some nodes , and the calculations freeze when it reaches the case "Modal"(Dynamic analysis: seismic). But when i ran my model without any type of release, the calculations went fine and without any warnings or errors so i know that the issue is not with the structure. And i need the "pinned-pinned" release for my columns. I don't understand what i'm doing wrong so if you could help me, i would really appreciate it. Thank you !

Check if you have any restrain for horizontal movements of the building. Perhaps you should define some bracings?
