Conntrans error with SENDING messages

Question

Hello everybody.
Still using a CRM 4.0 SR01 SP08 build, this time I am facing a Conntrans error : sending messages keep failing, while the reception process is OK.
If I select "SEND & RECEIVE", the SEND status becomes orange, RECEIVE is blue (OK) and I get in the summary the error related to the failure. Synchronizing another time gives the same result. When I close Conntrans, I get a "GUI MFC Error" crash popup.
If I select "SEND only", the SEND status stays gray and I get the error related to the failure. When synchronizing again, I get a "GUI MFC Error" crash popup while in the background the SEND status becomes orange, with the error related in the summary.
What we have tried so far is :
- deleting the 1st message from outbound queue (table = MW_Q_OUT, where MSG_ORDER = 1 ), gave no result
- testing connections to Comm Station : connection is OK
- launching the Check Environment from the Client Console : it reports that ADO version seems to be less than 2.5, and the registry setup is not complete (it misses HKLMsoftwaresapmtsoptions) but as all was working before, I don't think it is very important.
Here follow the data from the logs :

Answer 1

If you require Framework 2.0, upgrade to SP07. In this support package conntrans becomes compatible with 2.0.
EDIT: Sorry you are using 4.0, I meant SP07 for 5.0
