Sage 300 ERP 2014 and Crystal Reports exporting to file types

2 things -

1 - what happened to the REC format for exports?  is there a reason it disappeared?

2.  we are experiencing horrifically long processing times trying to export simple reports to CSV.  for example, I am running a Po Transaction List report containing about 600 records - it has been exporting for 21.5 minutes so far, and not yet done.  I had another user try this same report, and it finally crashed after 90 minutes.  We see this on numerous CSV exports, but no where near the same processing time if we choose excel or pdf.  We cannot use those, as the formatting in the excel export is garbage, and makes the data unusable.  Has anyone else seen this, and if so, is there a fix?
