Theres been a few posts about federal Efiling fine,  but MA state returns get the Error 54 message.  Something must have gone wonky in yesterdays update.

Have you tried REPAIR or REFRESH UPDATES yet?

Refresh can be found in the Updates drop down menu within ProSeries.

Repair updates is in the Windows Programs menu under each year or ProSeries.

Im honestly not sure what the difference is between them or if therye the same, why have 2 different names.
