I'm upgrading a Production version of our Reporting App that is using version 10.1.16.615 to the newer 188.8.131.52. There are numerous changes although I have not touched one type of reports, but with the new version .dll's I'm getting "Invalid value of report parameter" (see attached screenshot) on those. These reports all have approximately 50 sub-reports, logo's and the typical Header/Footer combination, in other words, they are complex reports. The other 2/3 of reports display correctly, but these give me the error.
Any help would be appreciated. Thank you,
