Journal

Has anyone had any problems with journal entries and assets? I did a journal in Myob to bring in an asset. The asset and value of asset is showing on the chart of accounts but the capital purchase isn't showing on my balance sheet or GST report. I tried to check the journal entry and now I can't find it. I searched all dates in case I entered it incorrectly and have tried everything. I can't do another journal or the asset and loan value will be double? I also had trouble last week journaling an asset and loan, the amounts showed up on the balance sheet as opposite what they should have (asset was showing as a negative), just to troubleshoot I re-opened the journal entry, swapped the figures around (Instead of debiting the asset and crediting the Loan, I credited the asset and debited the loan). Then the asset showed in sales? I've been using Myob since 2003, I know it like the back of my hand and am a qualified accountant. What is going on? Please help?
