I split this into a new topic, because your issue is not the same as the one in the thread you posted in, and the thread you had posted in was a year old.
Can you please answer a few questions so we can narrow down what the problem might be:
What version of windows?
What antivirus program? (some cause issues with RO)
When you say "freeze" what do you mean? Does just RO stop responding, or does the whole system stop responding?
Could the computer be overheating? If it's a laptop, when was the last time you cleaned the vents?
Is your computer stable when running other games?
I've got a bad feeling that this could be the sign of a hardware issue (overheating or bad RAM, most likely) or OS problem (damaged windows installation or malware infection).
