Meta-reg not working in Beta 3.0

Was attempting to run a simple meta-regression analysis (random-effects intended, but also checked fixed effect model)...Dependent variable was the weighted mean difference, co-variate was dose. Had no problem entering the co-variate but when I run the analysis, no sign of any meta-reg results in the analysis tab or the generated files. Tried running Meta-Analyst at home and at work (using Windows 2000 and XP).

Would be happy to make the data file available it you belive it would be helpful, just let me know who to mail it too.

In addition, no forest plot was generated in the initial analysis tab, but was generated in the analysis folder.
