What is the reason for the error that appears in Aspen?

Thread Content

As the title suggests, the errors are as follows. I encountered this issue while performing sensitivity analysis, and it also appears when entering settings for flowsheeting. Could it be that there is a problem with my installation? Waiting online, so anxious! Experts, please save me! ! !
