Pro/E Frequently Crashing During Use

Hey. I need a solution to frequent Pro/E Crashes. While working on assemblies or switching between a few open parts, I often receive this message.
The assemblies I am working on are not very large, but still this issue is arising very frequently. Can anyone help me with this problem with pro/engineer and tell me the reasons for this behavior? I am running WF5. Thanks in advance.
