Visual Basic 2005 Express edition error

I got the hotfixes today and installed them. They seem to help some with the crashes. But, I'm still having this issue:

I have a table in a SQL database I made with SQL express edition. I have the db connected to my program. In this table I have a field called Last Name. I place a listbox item on my form, then on the controls bind it to Lastname field. When I click on the small triangle, I select build query at the bottom. I use the query builder to build me a query. Everything is fine, until I go to add a second query. I then get this message:

Unable to write the custom tool "MSDatasetGenerator" to file Database1dataset.designer.vb. Process cannot access file because user by another process.

Also, then my dataset is gone from my project. I have to go through the steps to build it again and it won't let me, I get some other error I can't remember. I then get a error, VB needs to shutdown, do you want to send this to Microsoft. I click don't send and the program is still running. Everything appears to be fine. I go and try to create another query. It lets me build the query but after its built I get a code error saying my query isn't part of some tableadapter.

I'm really getting fed up with this. Has anyone else seen anything remotely close to this
