st: I get the error-message "file not estimates r(610);" when using - mi estimate -

Dear statalisters!

I'm doing a project about different phases of democratic transitions and their possible effects on economic growth. Because of the large amounts of missing data in econometric country data, I have decided to use multiple imputation to fill in the blanks. 

Unfortunately, I can't get stata to perform the mi estimations. I have used the following commands:

- mi query -

- mi set flong [or any other style] -

- mi register imputed [variables to be imputed]  

- mi register regular [other non-passive variables] 

- mi impute [tried a host of different methods like - regress - , - mvn - , - logit - etc.], add([usually 5, but other numbers have been tried]) 

All of the above works fine. Then I attempt the actual estimation...

- mi estimate: regress [or some other function] variable1 variable2 -

... and get this error message:

- file not estimates -

- r(610); -

I have encountered the same error with many different datasets; both original, simulated and hand-typed. As the generic error description says that the file is not of a stata-format, I have tried to use csv-datasets and datasets from different versions of stata. All to no avail. 

The original plan was to use the Amelia II-application for R to do the imputations and then have stata do the estimates (since I'm pretty non-fluent in R), so I have also tried using imported Amelia II-imputations with the - mi import - command. They too work fine up untill the estimation.  

I have combed the web and help-files for a solution to this problem, so I really hope you guys can help.

Thank you for your consideration!
