Error while running D/L ORs

Hello,

I am new to the MetaAnalyst software. I have been trying to run a simple DL OR. I enter my data and then run analysis->new analysis. I select Random(D/L) in the model box and then hit 'OK'.

Unfortunately, I get an error each time that states " Sorry, the metaanalyst has encountered an error while creating your report. Input string was not in the correct format".

I've reviewed my data entry and everything looks fine. I have even imported one of the sample datasets that comes with MA, and I received the same error. I am using the most recent version (Beta 3.13).

I welcome any suggestions - I would really like to use this software, but at this point I'm stuck!

TIA
