Not able to import citations from pubmed


I am using end note but i am not able to import a large volume data file (around 55000 citations) in end note. Is there a maximum number of citations that we can import in endnote

does anyone have a solution?

I have read that there is a import limit of 500, but I am not sure who imposes that limit.  (are you exporting to a file or using the Connection mode?)  

How many do you see that are imported?
