Error massege in Acad 14

[naghshe]

I'm using ACAD 14 on Vista. it happens sometimes that when i copy an object and want to paste it somewhere else on the drawing or when i want to mirror an object i get the error massege " unhanded Access Violation Exception at 2d3daah".
I have to abort and it asks me for saving. When trying to reopen the file it says the file is corrupt. i try to save every 30 seconds so that I don't lose data.
Is there any better solution to my problem?
Thanks in advance.

OK, I wouldn't normally suggest this as I understand the cost of ACAD isn't the sort of money you just find down the back of a chair, but really, R14 on Vista? It is really time to seriously consider an upgrade.

Back to the matter at hand, does the problem occur in specific drawings, or can it effect any drawing, even a new one? Have you recently installed ACAD on Vista, or have you been running it for a while?Did you experience this problem on your previous OS?

Is it just copy/paste and mirror or other commands? Are you working with native R14 drawings, or are they created in a newer package and saved back to R14?

Sorry for all the questions.

Cheers

Thanks for the fast reply.
The problem happens in the file I created before. It happend in another drawing as well. i have installed Acad on vista a month ago. i didn't have the problem on XP. The error massege apears sofar on those commands I mentioned. I open the drawing on Acad 2000, there i don't have problem openning it, then i save it back to 14 and continue working on my drawing in Acad 14 until it hapens again.I don't know what u mean by native 14.
Thanks

Go to http://usa.autodesk.com/adsk/servlet/ps/dl/index?siteID=123112&id=2334435&linkID=9240618#section9
and make sure that you have any hotfixes installed, etc.
When I said native, i meant created in R14, but you already answered that.

Can't think of any definitive problem at the moment, but will have a think about it. Am a little bit limited though, seeing how it is like a decade old..sorry.
