If you get a message similar to, "Could not create SSL/TLS secure channel."... please install a newer version of the .NET Framework from Microsoft. Vista can only use v4.6. Others should install the newest available, like v4.8.
EQ2 English Cannot Correctly Handle Names Ending in an "s"
As of the update today, ACT treats every spell or combat art for characters whose names end in an "s" as a separate character. The client text assigns the spell or combat art to a character using the possessive apostrophe "s" after the name, except for characters with names ending in an "s" where it only adds the apostrophe. That may be the issue.
