Data Sources Unaccessible [Archive] - ATLAS.ti Forum

Please help! Data Sources Unaccessible [Archive] - ATLAS.ti Forum:  I was unable to access my primary documents. In the Primary Doc Manager, the first three primary documents are in red color while the others are in black. Those three primary documents are in red in all backup HUs, so I cannot reload them from anywhere. I am unable to access those first three PDs which are very important :( All codes are still in the code manager but all quotations disappear from the output as you can see from the message below :(
If anyone knows how to fix this, please help suggest me and I will very appreciate that. I have time limit in collecting data as a student so please let me know ASAP. I am looking forward to hearing from all of you. Thank you in advances :D

I think I solved the problem:

When you right klick on the document that doesn't open, click on Data Source Management. Then you'll have the following option, which is a quote from the Help Menu:

Reset Last Access Information
To avoid accessing the wrong document, ATLAS.ti memorizes the certain state (size, date, path) of a document each time it was successfully accessed.

If ATLAS.ti detects a deviation between this access information and the referenced file, it assumes that it has been edited with another software or that it has been replaced with another version.

Because such changes bear the danger of corrupting the alignment of quotations, loading is rejected.

However, in some situations everything might be in good order. If you know for sure that the current state of the document would not render any of the work done in the primary document, like quote creation and/or coding, useless, you may force ATLAS.ti to accept the modified document as a legal primary document’s data source: choose Documents/Data Source Management/Reset Last Access Information. This synchronizes the access information stored in the HU with the actual access info of the file. An example of an action that does not negatively affect a PD is adding text at the end of a data document.

Note: With this powerful option you can make files loadable that could detrimentally affect your work. If you detect misaligned quotations after you chose this procedure, you know you did something wrong. If this has happened, you should either leave the HU without saving or correct all misaligned quotations manually.
