Importing Contacts into Zoho

Importing Contacts into Zoho

I have imported a couple small excel files (less than 100 contacts) into Zoho successfully.  I am now trying to import one with about 800, and Zoho seems to be stuck.  I get the "Uploading Import File" but it has been running for over an hour.  I am on the Professional Level, which says you should be able to do up to 10,000 contacts per batch.  Can anyone please advise for a solution?
