SSIS Package Hangs for a long time

every time I open a specific package it hangs for ages and eventually does process but I get this

Unable to cast COM object of type 'System.__ComObject' to interface type 'Microsoft.SqlServer.Dts.Pipeline.Wrapper.IDTSObject100'. This operation failed because the QueryInterface call on the COM component for the interface with IID '{203E24BD-5203-4C76-AFC7-7C8545EBA1A0}' failed due to the following error: The application called an interface that was marshalled for a different thread. (Exception from HRESULT: 0x8001010E (RPC_E_WRONG_THREAD)). (Microsoft Visual Studio)

I've seen people fix this by registering the dts.dll: close the solution, open the command prompt and type "cd C:\Program Files\Microsoft SQL Server\90\DTS\Binn" and press <Enter>, then type "regsvr32 dts.dll" and press <Enter>. You should get a "dll registered" notice. Open the solution and see if it works for you.
