Recordset is not updateable in Access 2010 but works in previous versions

Question

I have a database that writes data from SQL tables to unbound controls on an unbound form. This database has been in place for years and has worked great. We recently just upgraded to 2010 and now I' m receiving an error message saying that the recordset
is not updateable. This is the same exact code and settings and everything else that has worked in 2007.
I know there are other posts on here that addressed this but none of the recommendations have solved my problem. I've tried changing the forms to dynaset(inconsistent updates), etc. and nothing.
The actual SQL is all in VBA where it's running the SQL commands against SQL Server and writing the data to the unbound fields and then also writing it back to the tables. As I said, this has been in place for a number of years and has always worked great
but I just can't put any rhyme to reason why it's not working in 2010.

Hi,
Based on my research, here’s the information about this error message:
A recordset is never updateable when:
It is based on a Crosstab query.
It is based on a Union Query.
It is an Aggregate Query that calculates a sum, average, count or other type of total on the values in a field.
It is an Update Query that references a field in the Update To row from either a crosstab query, select query, or subquery that contains totals or aggregate functions
     Note: By using a domain aggregate function in the Update To row of an update query, you can reference fields from either a crosstab query, select query, or subquery that contains totals or aggregate functions.
It is based on a Query that includes a linked ODBC table with no unique index.
The database was opened as read-only or is located on a read-only drive.
It is a SQL pass-through query.
It is a query whose UniqueValues property is set to Yes. (That is, it is a query with a DISTINCT predicate.)
Cartesian Joins(that is, a query that includes more than one table or query, and the tables or queries aren't joined by a join line in Design view.)
Query based on three or more tables in which there is a many-to-one-to-many relationship.
     Note: Though you can't update the data in the query directly, you can update the data in a form or data access page based on the query if the form's RecordsetType property is set to Dynaset (Inconsistent Updates).
Calculated fields. Even if the query itself is updateable, if a column in a query is based on a formula, the field cannot be updated. However, if the other fields in the formula are updated, the calculated field
will automatically update.
Recordsets Are Updateable Under Certain Conditions
1. Query based on a Join of tables with no Relationship.
Problem: If a query is based on two or more tables that DO NOT have a relationship established (with Referential Integrity enabled), the query will be non-updateable.
Solution: Create a Primary Key or Unique Index on ALL of the fields used in the Join on the "one-side" table. To be clear, this means ONE primary key or unique index based on all of the fields, not separate indexes
on each field.
In a query based on a Join of tables with a one-to-many relationship (1:M), you might not be able to edit the data in one or more fields. As the following examples show :
2. Join field from the "one" side.
Problem: If you have a 1:M relationship created between two tables, you cannot change the primary key field (used in the Join) of the table on the "one" side of the relationship.
Solution: Enable cascading updates between the two tables.
3. New records, if the "many" side join field doesn't appear in the datasheet
Problem: In a query based on a 1:M relationship, you can create a new record and fill in the fields that come from the "one" side table, but if the join field from the "many" side table is not visible in the
query (that is, the foreign key), you cannot add data to the "many" side fields.
Solution: Add the join field from the "many" side table (ie, foreign key) to your query to allow adding new records.
4. New records on the "one" side that are duplicates of other "one" side records.
Problem: When adding a new record, if you try to type into the "one" side fields, you will be attempting to create a new record. Even if you use the same primary key values, it will give you an error.
Solution: Add a value to the "many" side join field (foreign key) that matches the "one" side join field (primary      key) of an already existing record. The "one" side values will simply
appear.
5. Join field from the "many" side, after you've updated data on the "one" side
Problem: If you are currently editing fields from the  "one" side of the relationship, you cannot change the "many" side join field (foreign key).
Solution: Save the record; then you'll be able to make changes to the "many" side join field.
6. New records, if entire unique key of ODBC table isn't output
Problem: This is different than #5 under Never Updateable. In this case, the primary key of the linked ODBC table exists, but is not added to the query.
Solution: Select all primary key fields of ODBC tables to allow inserts into them.
7. Query does not have Update Data permissions
Problem: Query (or underlying table) for which Update Data permission isn't granted.
Solution: To modify data, permissions must be assigned.
8. Query does not have Delete Data Permissions
Problem: Query (or underlying table) for which Delete Data permission isn't granted
Solution: To delete data, permissions must be assigned.
